Hi Mark, No licensing was involved. I am willing to give the design to anyone. They asked :) The Sydor implementation has additional features; a built-in power supply and a bias supply. Not sure what else they changed. Pete.

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: http://sydortechnologies.com/files/Data-Sheet-SI-EP-B4.pdf 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.

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). Thisdevice 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_EMin 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 TRIUMF, Vancouver, Canada -- D.
