1. Looking at the beam position on the screen and by the beam current on FC, try to align beam line. The goal is to center the beam on the screen, and maximize the FC charge as high as possible.
 
−
 
 
−
2. Reduced the mis-steering at the quadrupole by tuning steerers in the linac.
 
−
 
 
−
3. Optimize steerers, solenoids in linac to get a round electron beam shape and no steering at the quadrupole.
 
−

−
Energy is set by bending the beam to dipole at specific current.
 
−
 
 
−
Set dipole current for 10 MeV, and bend the beam. Tune the beam energy, until we see peak current at the 45 degree Faraday cup.

=== Emittance measurement at 10 MeV ===
 
−
 
 
−
This is scan for 10 MeV beam. 40 mAmps peak current. Q1 is on, All other quads are off.
 
−
 
 
−
1) Scan from -5 Amps to 5 Amps. Increment at 0.2 Amps.
 
  
−
3) Name images by numbers start from 1. Then go on. Like: -5 Amp is 1, -4.8 Amp is 2, and so on til 5 Amp is named 51.
+
== Triggering  ==
  
−
4) Scan multiple times from -5 to 5 Amps, and put them in different folders. Name folder by number, like 1, 2, 3 etc. After finishing one scan go back to -5 Amps. When going back take small steps (like 1 Amp), do not jump from 5 Amps to -5 Amps directly. After reaching back to -5, wait for few moment (like 10 s).
+
We sent the pulse from gun trigger to a pulser. We delayed the pulse 8 micro-second, created 8 micro-second wide pulse with 4 V amplitude. This pulse triggered the camera. In following figure camera trigger pulse and signal 45 degree Faraday cup is shown.
  
−
5) For each time, take back ground images. It should be done when RF is on and gun is off.
+
[[File:hrrl_Apr26_2012_Cam_Trig.png | 400 px]]
  
−
6) After the scan take a scope image for the current of the FC after the OTR screen. Lower the current, so the vacuum window do not heat up. This step is to check energy.

Coil current vs Electron Beam Energy

Coil           En                Mod HVPS Grid Set
Current 
(Amp)          (MeV)
6.50 	 	3.49960871
15.25 	 	8.04790047        
15.3                             4.12  (En Switch off)
24 	 	12.5378648        4.30  (En Switch off)
33 	 	15.6004336        4.84  (En Switch off)

Preparation

[Check List]

1. Magnets (on/off)

2. Camera: (on/off) (Sync) (shielding)

3. Flags: (In/Out)

4. Farady Cup: hocked up?

5. Blank off for camera on?

6. Gas bottle for valve full?

7. Gas bottle for flags full?

Distances

Distance from the front of the first quad,Q1, to the OTR screen is [math] 342.5~cm[/math]. Then the distance from the center of Q1 to the screen is [math] S_{12} = l = 342.5 - 15/2 = 335 ~cm[/math].

Distance from End of first dipole D1 to the Faraday Cup,FC2, is [math] 55cm[/math]

15.6 MeV Setting

Quad Scan is done here with Q1.


Energy switch changed to low energy setting. Part of the cavity is grounded.

Gun has been up to air for 3 times. It could be oxidation, contamination. Or it could be gun died, less likely. Roasting the gun to burn off the contamination is an idea. Chad just roasted gun for with higher current, we saw gun current increased many times. We will leave roasted for one night.

Camera Triggering

Triggering

We sent the pulse from gun trigger to a pulser. We delayed the pulse 8 micro-second, created 8 micro-second wide pulse with 4 V amplitude. This pulse triggered the camera. In following figure camera trigger pulse and signal 45 degree Faraday cup is shown.
