  2   Mon Oct 12 11:50:52 2015 Sarah Lonsdale05/10/15 Pulser, Wiring information and DAQ initial set up

600mV in 50ohm coax with 25 hz pulser (positive signal) - see 2015-10-05_15.19.54.jpg and 2015-10-05_15.22.46.jpg



Leakage currents on detectors:

In air
10v: 0.03 micro amp det 1 leakage -dE
132v: 0.47micro amp det 2 leakage- E det

In vacuum
DE 0.04 micro amp
E 0.46 micro amp

Same size of signal at ADC hence 50 ohms coaxial.

The following channel explanations refer to cables at control area (not vault) see (
2015-10-05_15.19.54.jpg) for full wiring information.


dE det= DEED 0 to -2V full scale, Lower limit 1800mV, Threshold 0V, thresh neg, pre 1024, post 2048, 20ms window, sample rate 225 MS/s
- L6D6 A = de 4
- L6D6 B = de 5
- L6D6 C = de 6
- L6D6 D = de 7
- LaBr 3 = de 8
- 21 = de 9

E det front= EFED 0 to -2V full scale, Lower limit 1800mV, Threshold 0V, thresh neg, pre 1024, post 2048, 20ms window, sample rate 225 MS/s
- 10 = Ef 3
- 12 = Ef 4
- 13 = Ef 5
- 14 = Ef 6
- 15 = Ef 7

E det back= EBED 0 to +2V full scale, Lower limit -200mV, Threshold 0V, thresh pos, pre 1024, post 2048, 20ms window, sample rate 225 MS/s (except EBED 5,6,7 which MUST be 900MS/s due to beam pick up signal)
- 16 = Eb 3
- 18 = Eb 4
- 20 = Eb 5
- 38 = Eb 6
- 40 = Eb 7

 20 micron (see 2015-10-05_12.46.59.jpg for detailed information) and 500 micron detectors

Testing preamps using pulser through common wire to both sets of preamps (see 2015-10-05_13.12.01.jpg).

64 x 14mA pos signals 15V
64 x 4mA neg signals 15V (see 2015-10-05_12.02.00.jpfor example on oscilloscope)

Sample has 105 microgram Li-6 (LiF - 95% enriched) 105 micron thick (2015-10-05_12.12.15.jpis Li-6 side up, 2015-10-05_12.12.26.jpis Li-6 side down... do not mix up!)

dE uses 22, 23 on ribbon connector, E 24, 25
dE from bias supply 2, E from bias 1

de and E pos signals needed to be inverted using jumpers. de negs not used, only 16ch (see 2015-10-05_14.59.12.jpg)


de first and last (0,15) are noisy- don't use. E detector ch 0 doesn't work.
Channels used dE 4-9, E(pos) 3-7 and E(neg) 3-7 (see
2015-10-05_15.11.37.jpg and 2015-10-05_15.11.44.jpg)
