A while back I scoured the TB and control & driver circuits patent and came up with the following info:
Refer to Tech Brief Figures 3-2, 3-4, 3-5, 3-6 and Patent WO 92/07861
Circuit K1=Safety Control Circuit
Circuit K2=Variable Pulse Frequency Generator
Circuit K3=Gated Pulse Frequency Generator
Circuit K4=Cell Driver Circuit
Circuit K5=Voltage Intensifier Circuit
Circuit K6=?
Circuit K7=Laser Accelerator/Distributor Optoschmitt (Photodiode)
Circuit K8=Analog Voltage Generator
Cirucit K9=Voltage Amplitude Control
Circuit K10=Injector Circuit
Circuit K11=Acceleration Control Circuit
Cirucit K12=Laser Distributor
Circuit K13=Gas Injector Cirucit
Circuit K14=Pulse Indicator Circuit
Circuit K15=Gated Frequency Oscillator
Circuit K16=Dual Regulated Power Supply
Circuit K17=?
Circuit K18=?
Circuit K19=Exhaust & Air Gate Control Circuits
Circuit K20=Summing Circuits
Circuit K21=Phase Lock Loop Circuit
Card L1=Variable Pulse Frequency Generator (Circuit K2)
Card L2=?
Card L3=Gas Injector Card (Circuits K10, K13)
Card L4=Gated Pulse Frequency Generator (Circuit K3)
Card L5=Acceleration Card (Circuit K11)
Card L6=Dual Regulated Power Supply (Circuit K16)
Card L7=Gated Frequency Oscillator (Circuit K15)
Card L8=Laser Distributor Optoshmitts (photodiodes) (Circuits K7, K12)
Card L9=Safety Control Circuit (Circuit K1)
Card L10=Laser Accelerator Optoschmitts (photodiodes) (Circuits K7, K12)
Card L11=Analog Voltage Generator (Circuit K8)
Card L12=Voltage Intensifier Control (Circuits K4, K5, K9, K14, K21, and the EEC per Fig 3-2 Tech Brief)
I need help as the list is not complete. I have not determined what circuits K6, K17, and K18 are. I have not determined which circuits are on Card L2. And I have not determined which Card(s) the following circuits are on: K6, K17, K18, K19, K20.
I know of one cirucit for sure which is missing and it's probably K6, K17, or K18. That is the Gas Feedback Control Circuit (Figure 11) from the Control & Driver Circuits patent WO 92/07861
