public final class PIDsimulation

extends java.lang.Object

This class will execute a process to simulate the focal plane detector. It is based on the code written by Kazim Yildiz for the Vax machines, which are now dying. It was too difficult and time-consuming to figure out why Kazim's code wouldn't run properly on the Solaris machines.

2

"Dead" gas region up to start of cathode

3

1st part of cathode

4

Anode, 2nd part of cathode

5

3rd part of cathode

6

"Dead" gas region between cathode and exit foil

7

Exit Foil

8

Foil on the scintillator

9

Scintillator

Parameters:

name - the name of the input specification file
