='''Initial Experiments'''=

[[CH PAS He3 Poly Boration Study]]

[[CH He3 Pre-amp Noise Investigation]]

='''Experimental Setup'''=

Detector is mounted on 3D printed stands located at each end of the 20" He3 tube

The stands are ABS plastic

The entire setup is on top of BorAl plating placed on top of a plywood workbench

Front face of poly structure is 9.5" to closest part of detector tube

=='''Polyethylene Structure'''==

This section to include type of poly, location, source-detector distance, images, etc

=='''Detector'''==

Include images, model/serial number of detector, physical parameters, etc

'''Ortec 142PC Pre-amp'''

Pre-amp for the He3 tube

'''CAEN Quad Linear Fan In - Fan Out Model N25 Tag #15687'''

* The fan in/out is used to duplicate the pulse to run the spec amp and watch the signal on the scope for any anomalies. 

* The fan in/out is also used to invert the signal from the spec amp to send a negative pulse to the discriminator to trigger the scalar.

'''Ortec Spec Amp Model 672'''

* 10x Course Gain

* 1x Fine Gain

* 0.5us Shaping Time

* Uni Shaping: Gaussian

* Input: Norm (+)

* Output: Unipolar

* Manual Pole Zero adjustment

'''Lecroy Discriminator Model 821 Serial #B16303'''
