Results of the Test of New Target

Befor we install the new target in our detector on July 18, 2001, we set up to test the new target in studio B.

Results from Cs-137 Source

At 900 of HVs, we now have the following results for the Cs-137 662 keV endpoint voltages:

TGT Module 662 keV endpoint

T0 200 mV

T1 200 mV

T2 215 mV

T3 225 mV

T4 190 mV

T5 205 mV

T6 132 mV

T7 190 mV

T8 205 mV

TGT Module	662 keV endpoint
T0	200 mV
T1	200 mV
T2	215 mV
T3	225 mV
T4	190 mV
T5	205 mV
T6	132 mV
T7	190 mV
T8	205 mV

Cosmic Results

We also tested the responses to cosmics of target 0, 1, 3, and 5. the trigger used to test target 0 is:

T1*T3*not(T2+T4)

the trigger for target 1 is:

T0*T3*not(T2+T4)

The trigger for target 5 is :

(T1+T4)*T7*not(T6+T8)

The results are displayed in the attached ps file. The tgt 0 was labeled as v0, tgt 1 was labeled as v1, tgt3 was labeled as v3, tgt 5 vwas labeled as v.
