=HV burn in=

Begin burn in after at least 3 volume changes.

[[File:High_Voltage_Region_1_Sector_1_data.xls]]

Step 1: Set Voltage to 50 volts on all channels. Probe HVB to be sure that all sense, field, and guard wires have a voltage. (You should set current threshold to 10 microAmps on the HV supply)

Step 2: While monitoring the current, ramp the HV to the following

G:F:S= 525,-700,700

Step 3: Begin to take data recording the time and sense wire current as you ramp up the sense wire HV to 1400 volts while restricting the current draw to less than 10 micraAmps.

keep current under 10 micro amps while moving sense voltage up to 1400

=Measured Sense wire output=

==Using ADB crate==

(TDC1190[106]-TDC1190[104] = 3 ns) => PMT F1 - PMT I2 = Two PMTs that are on separate paddles and adjacent.

(TDC1190[106]-TDC1190[107] = 40 +/- 10 ns) => PMT F1 - PMT F2 = Two PMTs that are on the SAME paddle. Not sure why there is a 40 ns offset but the 10 ns wide range is because the paddles are about 70 cm long ( see [[CLAS12R1_CosmicTestStand#Scintillator_Timing_Studies]])

|-
|4008 || 4/11/13 || set ADB threshold to 100 , installed all 6 STB connectors, key was on the left as you face the ADC crate. Two top PMTs and one bottom PMT were in coincidence. The rate was about 0.5 Hz. at 9:41 on 4/12/13 I observed no voltage coming out of the discriminator monitor, the fuses were NOT blown. Hits seemed to disappear in the data. I recycled the ADB crate power and saw 100 mV on the discriminator monitor. Start a new run 40009

==== HV-vs- Efficiency====

Keep the discriminator constant and change the HV.

The HV should stay at the ratios of S:F:G=1:0.5:4/11

==Linfit to layer -vs- y distance==

The staggered layering of the cells in a single drift chamber super layer results in cells that are offset from each other by 30 degrees (PI/6). Below is a event illustrating the observation of ionization signals observed by 6 of the 96 instrumented wires caused by the passage of a cosmic ray.

A coordinate system is established which defines the X-direction along the depth of the superlayer and the Y-direction along the endplate of the chamber. The chamber is facing towards the sky so cosmic rays may enter the front face of a chamber. The location of the cells, with this coordinate system, may be determined using the equations below along with the row and column of the hit.

:TDC2row[]={5,3,1,6,4,2};
:x=TDC2row[TDCChannelNumber%6)];
:y=(TDCChannelNumber/6+1)*(1+0.25*sin(PI/3)/(1+sin(PI/6)))=(TDCChannelNumber/6+1)*(1.14434);

;if the layer number (X) is even then the Y position center needs to be shifted backward in the Y direction by
:y[HitNumber]-=sin(PI/3)/(1+sin(PI/6));

The uncertainty in the position is

:DeltaX=1/sqrt(12);
:DeltaY=sin(PI/3)/(1+sin(PI/6))/sqrt(3);

TDCChannelNumber is used to locate the row and column of the wire that saw an ionization signal.

</pre>

A linear fit is performed assuming that the ionization event occurs in the center of the cell. Later a drift time function should be used to offset each hit from the center according to the drift time function that uses the TDC measurement as an input.

Below is the incident cosmic ray angle when only 6 hits occur in the chamber for run [[CLAS12_r4135]]

Bulacarl: /* Testing procedure */

==Testing procedure==

Things that may cause "noise" that are actually due to your testing setup:

* STB boards not securely attached to chamber. Make sure center screws (ones attaching directly to the chamber, not the nylon stand-offs) are tightened to 14 in. lb's.

* Scope's termination set to 1Mohm. Set the scope to 50ohm termination.

* Lower bandwidth of 1 Ghz scope to 200 Mhz. This attenuates peak height, but also rejects high frequency noise and reduces the noise level from 55-65 mV to ~11-15 mV.

* Extra movement a vibrations in the amplifier.

==Testing procedure==

Things that may cause "noise" that are actually due to your testing setup:

* STB boards not securely attached to chamber. Make sure center screws (ones attaching directly to the chamber, not the nylon stand-offs) are tightened to 14 in. lb's.

* Scope's termination set to 1Mohm. Set the scope to 50ohm termination.

* Lower bandwidth of 1 Ghz scope to 200 Mhz. This attenuates peak height, but also rejects high frequency noise and reduces the noise level from 55-65 mV to ~11-15 mV.

Things that may cause "noise" that are actually due to your testing setup:

* STB boards not securely attached to chamber. Make sure center screws (ones attaching directly to the chamber, not the nylon stand-offs) are tightened to 14 in. lb's.

* Scope's termination set to 1Mohm. Set the scope to 50ohm termination.

* Lower bandwidth of 1 Ghz scope to 200 Mhz. This attenuates peak height, but also rejects high frequency noise and reduces the noise level from 55-65 mV to ~11-15 mV.
