Design

Emittance Desien.png

New deisign: We changed to use just one magnet.

File:Emittance Test Optim File.txt

HRRL had steer magnets on itself. We don't need external steer magnets. But Dr. Chouffani said that we might need them after quads, if the quads are not on axis. He will think about it.

Constructed Beam Line for Emittance Test

Vacuum pressure on the beam line is less than [math] 10^{-8} [/math] torr (on 2010-July-7th).

Leveling Survey

Downstream of the beam up by 2.6 mm.

Constructed Beam Line for Emittance Test Leveling Survey.jpg



How to do Leveling Survey and Alignment with Theodolite on e- Beam Line

A. Leveling Beam Pipe

1. Put the theodolite as high as the center of the beam line at upstream. Turn theodolite up and down. If the up angle is equal to down angle from the center of the pipe, theodolite is exactly as high as beam pipe. If not, adjust theodolite, until up and down angles are equal.

2. Once first step finished, then rotate theodolite horizontally to down stream. Turn it up and down, if up and down angles are not equal, adjust the stand till they are equal.


B. How to Make Sure the Quad is Perpendicular to the Beam Line

If the distances between quads and end of cavity at any given points are equal, then quad and end of cavity are parallel. Pipe is perpendicular to the end of the cavity, thus, magnet would also be perpendicular to the pipe.

I will find at lest three random points quads and three corresponding points at the end of the cavity, make sure they are equal, then I can say, magnet is perpendicular to the beam line.

I am planning to stick a metal ruler two, so two faces are parallel.


C. Centering the Quad Magnet with Theodolite

Vertical Centering

1. Finish the step 1 in A.

2. Then turn up the theodolite from the upper edge of the pipe to the magnet hole, call this angle upper angle. Do the same at lower part, call it lower angle. If the this two angles are not equal adjust the stand till they are equal.


Horizantal Centering

We know the diameter of the pipe [math] d_p [/math]. So, we can calculate from the pipe to the edge of the quad as:

We need to make sure this distance is same when measure it horizontally, so that our quad is centered on the pipe. I am going to use a ruler to ...(thinking)


July 2010 Run

Initial Accelerator Settings

E = 10 MeV [math]\Rightarrow[/math] Control Voltage= 4.09 V

Pulse Width <= 50 ns

Average Beam Current = least amount needed to light up YaG crystal, start at 1 mA and Rep rate of 100 Hz.

At the same time we want to do radiation test on HRRL. This is for predicting the radiation after shifting cavity to new position. Radiation test run plan is at: [1]

7/26/10

Alignment check

1.) Survey the Quad to be sure it is centered on the beam pipe

2.) survey the flag to determine if target is centered on the beam pipe

Transmission tuning

1.) Using the quads and accelerator coils, focus the beam on the YaG crystal to as fine a spot as possible. Monitor the FC during the focusing.

changed control Voltage from

Control Voltage= 4.9 V [math]\Rightarrow[/math] E = 16 MeV

to


4.09 V [math]\Rightarrow[/math] E = 10 MeV


Tune the 4 accelerator coils for max transmission.

We want to maximize the current reach the Farady Cup. This can be determined by the ratio on Channels of FC and Gun Current.

Gun current is the current on the pick up coil, which is input current for cavity. Current on Farady cup is the current reach the end of the beam line (FC is at the end of the beam line). We want to maximize the the ratio of Farady cup current to Gun current (FCC/GC), so there are more electrons will make it to the target. Thus, we enlarge our positron yield.

Basic principle: Fix three coils, change one till it maximized.

After image manipulation in GIMP to remove spot from the filament, Arne obtained reasonable projections for horizontal and vertical beam sizes ( < 2 mm). The quad was off, low rep rate to avoid saturation, 10MeV. This was the spot for the initial setup on Wednesday. Image fit snapshot 20100728 1720.jpg


Electron beam deflection due to Earth's B-field.

It appears the the image from electrons hitting the YaG crystal is offset (to the right) compare to the image from the filament which appears near the center of the cross hairs.

Is the earths Magnetic field causing the electrons to move this far beam right?

[math]B_{Earth}[/math] = 0.00005 Tesla ( [math]\frac{ \mbox{kg}}{\mbox{C}\cdot \mbox{s}}[/math]) = 0.5 Gauss

E_{electron} = 10 MeV = Pc [math]\Rightarrow[/math] P = 10 MeV/c

Estimation using Classical Lorentz Force (forget about angle of B and V)

[math]\vec{F} = q \vec{v} \times \vec{B}[/math]

assuming [math]v[/math] and [math]B[/math] are orthogonal then we get the cyclotron radius


[math]F= qvB = m\frac{v^2}{r} \Rightarrow r = \frac{qB}{mv}[/math]

[math]r = \frac{(1.6 \times 10^{-19} \mbox{C}) \times ( 5 \times 10^{-5}\frac{\mbox{kg}}{\mbox{C} \cdot \mbox{s}})}{mv}[/math]

[math]mv = P = 10 \frac{ \mbox{MeV}}{\mbox{c}} = 5.6 \times 10^{-21} \frac{\mbox{kg} \cdot \mbox{m} }{\mbox{s}} [/math]


[math]\Rightarrow r = 700 \mbox{m}[/math]


Now some Geometry.

Assuming the orbit is a circle with a 700 m radius, then the question becomes how far does the electron move to maintain the orbit if it travels 1 m in a straight line.

let

[math]r[/math]= radius of circle

[math]l[/math]= distance along the beam line

[math]d[/math] = deflection due to gravity

Note
[math]l[/math] is a tangent to the orbit

one can construct a right angle triangle with side of length d, the [math]l[/math] as the base and [math]r+d[/math] as the hypotenuse.

Then Pythagorean's theorem gives

[math]r^2 + l^2 = (r+d)^2[/math]

Giving

[math]d^2+ (2r)d +l^2 =0[/math]

using quadratic formula you get

[math]2d = -(2r)/2 \pm \sqrt{(2r)^2 + 4\frac{l^2}{r^2}}/2[/math]


since l/r is very small (1/700) we can approximate this as

[math]d = -r \pm r \sqrt{1+ \frac{l^2}{r^2}} \approx \frac{l^2}{r} = \frac{l^2}\frac{P}{qB}= \frac{qBl^2}{P}[/math]

for 10 MeV and a 1 m long beam pipe

[math]d = (l\mbox {m})^2 \frac{(1.6 \times 10^{-19} \mbox{C}) \times ( 5 \times 10^{-5}\frac{\mbox{kg}}{\mbox{C} \cdot \mbox{s}})}{ 5.6 \times 10^{-21} \frac{\mbox{kg} \cdot \mbox{m} }{\mbox{s}} } = l^2 \times 1.42 \mbox{mm}[/math] where [math]l[/math] is in units of m

Radiation Footprint Measurements

Spent the remaining beam time doing radiation footprint measurements.

HRRL_radiation_tests#Run_Plan

7/29/10

Today we first tune up the beam for max transmission.

If the above calculation is correct we can expect the electron beam to move at least 2 mm away from the center of the FC. We could test it the Earth's B-field is the cause of the deflection by watch the deflection as a function of the beam energy. If we had enough [math]\mu[/math]-metal we could wrap the beam pipe in it and see if the deflection goes away.

Radiation Footprint Measurements

spent noon to 3pm on radiation measurements below

HRRL_radiation_tests#29_Jul_2010

Earth's B-field effect

It the above calculation on the effects of the Earth's Magnetic field on a the electron beam is correct then we should see the amount of deflection depend inversely on the electron's momentum (1/P).

So lets take a few pictures at the energy exterma to see how far the electron spot moves away from the filament image on the crystal.


E beam (V gun) YaG picture Beam Spot posiiton (arb offset)
5 100 px
10 (4.09 V) BeamSpot E10 7-29-10.jpg -31.8 [math]\pm[/math] .1 mm
16 (4.9 V) BeamSpot E16 7-29-10.jpg -32.0 [math]\pm[/math] 0.1 mm


We did not see the beam spot move when the energy was changed from 10 MeV to 16 MeV, but going to lower energy definitely moved the beam spot farther away from the center filament image that is located on the YaG crystal cross hairs.

Maximize Transmission

Change the linac coils to determine a setting which delivers the maximum current to the FC and has a reasonable spot size on the YaG viewer.


Coil 1 upstream left/right (A) Coil 2 upstream UP/down (A) Coil 3 downstream up/down Coil 4 downstream left right Scope Picture Gun Current FC current Ratio YaG Image
0 0.6 1.8 2.7


Coil 1 upstream left/right (A) Coil 2 upstream UP/down (A) Coil 3 downstream up/down Coil 4 downstream left right Scope Picture Gun Current FC current Ratio YaG Image
0 0.6 1.8 2.7 100px 100px



a.) Does a small beam spot size on the crystal give maximum FC signal?

b.) Is there a point where the spot size changes and you can't resolve a change in the FC output?

c.) Remove the YaG target and determine if above observations are unchanged.

Pickup Coil Calibration

2.) After tuning the beam to deliver the Maximum beam current to the FC, measure the FC and green pickup coil output as a function of current by integrating the pulse with an oscilloscope.

6 HRRL Emit test PickUp Coil Calibration 6mA Scope.jpg HRRL Emit test PickUp Coil Calibration 6mA Spot.png

a.) does the FC output change with rep rate? It should not but maybe there is loss at high rates?

Quad scan

Tune the beam so a change in the quad B-field does not cause a deflection.

First attempt to measure the spot size change as a function of Quad current

Quad Current Beam Spot RMS (0 degrees= Left/right) Beam Spot RMS (90 degrees= Up/Down)
(Amps) (mm) (mm)


Shall we do both polarities?

Imaging

Background subtraction

The filament produces at least a 2 mm diameter spot on the YaG crystal. Beam dominates the image.

7/30/10

At 4pm yesterday we attempted to measure the emittance at high currents of 10 mA, previous measurements were at 0.3 mA. The beam spot became larger than the 1" YaG target holder. This would make emittance measurements impossible.

In order to measure the emittance above 1 mA we will need to insert a doublet as close to the accelerator entrance as possible. Since this would not be done by today we decided to cancel today's beam time and work on the next emittance measurement.

The YaG camera saturated at about 0.6 mA of beam current (our measurements were made at about 0.3 mA). Perhaps we should use a thin Aluminum target instead of the YaG crystal for high current measurements.

We were able to Trigger the GigE camera. We should use this next time.

Imaging scratch area

After image manipulation in GIMP to remove spot from filament. Obtained reasonable projections for horizontal and vertical beam sizes. The quad was off, low rep rate to avoid saturation, 10MeV. This was the spot for the initial setup on Wednesday. Image fit snapshot 20100728 1720.jpg
