Hi Rod,
The APS electrometer is no longer supported or available. The designer has left the APS, and the design has some problems which will not be fixed. I don't think any of these units are still be used.
The NSLS design is now sold commercially by Sydor:

I think BNL licensed this design to Sydor, so you will need to ask Pete Siddons if the license allows BNL to openly share the design.

Subject: Devices supported by quadEM
Hi all.
I've just started reading Mark Rivers' documentation for the quadEM
device support package. In there, he mentions that there is support for
two devices that are products of accelerator labs:
> The NSLS Quad Electrometer (called NSLS_EM in this document). This
device consists of a 4-channel digital electrometer unit with Ethernet
communication. The device provides 4-channel current measurements at
up to 2500 Hz.
> The Quad Electrometer built by Steve Ross from the APS (called APS_EM
in this document). This device consists of a 4-channel digital
electrometer
unit and 2 VME boards. The device provides 2 readings per diode at
up to 813 Hz.
Can anyone tell me whether those devices are available in any form? Open
hardware design, outright purchase, evaluation loan, etc? If anyone
knows a contact person regarding either one, that would be
great to know.
Thanks.
Rod Nussbaumer
