Inventory of the Simard Sputtering Power Supplies
    ---------------------------------------------------


                                           Original Rev.  18-Feb-2022
                                            Current Rev.  14-Apr-2022


I will list all of the Simard power supplies that I know
about.  First I will list the supplies that are currently
connected to a gun and then list the other supplies that
I've spotted in various places.


Gun "A"
-------

  Filament & Anode Supply:   Simard Model PD-250    SN PD2541
                             Status: hopefully repaired and
                                     now working OK again

            Target Supply:   Simard Model TS-2      SN TS2032
                             Status: assumed to be working OK


Gun "B"
-------

  Filament & Anode Supply:   Simard Model PD-200    SN PD2013
                             Status: assumed to be working OK

            Target Supply:   Simard Model TS-2      SN TS2041
                             Status: assumed to be working OK


Gun "C"
-------

  Filament & Anode Supply:   Simard Model PD-200    SN PD2014
                             Status: assumed to be working OK

            Target Supply:   Simard Model TS-2      SN TS2042
                             Status: assumed to be working OK


Gun "D"
-------

  Filament & Anode Supply:   Simard Model PD-20    SN 18384
                             Eratron Model PD-20-MF
                             Status: assumed to be working OK,
                                     missing its 10-t control
                                     knob for Filament Current,
                                     has it always been missing ?

  Igniter Box,  i.e. the extra metal box sitting behind this
  PD-20 supply is an "Igniter Box" from Simard that allows a
  PD-20 supply to work in the same way as a PD-200 or PD-250
  supply with respect to starting and re-igniting the plasma.

            Target Supply:   Simard Model TS-2    SN 2031
                             Status: assumed to be working OK,
                             for some reason there is no "TS"
                             in the serial number on this
                             power supply




Spare / Other Power Supplies:
-----------------------------

  Rm B148  on the floor behind the sputtering electronics racks
  Simard Model PD-20    SN 13279    Eratron Model PD-20-MF
  Status:  has a 3 pin output connector, has a broken front
           panel Volt meter, it's missing fuses and terminal
           screws,  works/broken ?


  Rm B148  on a table in the front of the room
  Simard Model PD-20    SN 18187    Eratron Model PD-20-MF
  Status:  has a 3 pin output connector, otherwise its
           status is unknown,  works/broken ?


  Rm B112  on the counter
  Simard Model PD-250    SN PD2511
  Status:  was brought to Rm B112 to use as a parts source for
           the repair of PD-250  SN PD2541,  it has a broken
           Plasma Voltmeter,  it's now missing its igniter relay,
           an internal cable, and snubber networks,  whether
           or not it has other problems is not known.
  Status:  This supply has been repaired and was given a final
           test on 14-April-2022 using the dummy load.  All
           functions were tested except for actually using the
           remote control panel.  Repaired items include: front
           panel Anode Voltmeter, Igniter Relay K405 and its
           Snubber circuits, 24 VAC Transformer K303, Main
           Control Board items: Relay K1 and Electrolytic Caps,
           and a replacement Cable from the Control Brd to the
           Anode Voltage and Current Sensors.




Summary of "Pinch Points":
--------------------------

  - As far as I know there are zero spare Target power
    supplies - either working or not.

  - As far as I know there is only one of the separate
    Igniter Boxes  so that at the most the running 4 gun
    system can use only  1 of the 3  PD-20 power supplies.
