Hi Marychris,
can you please send this to your technical folks and ask them to get back to me?
The system I am using should still be under warranty.
I am having weird behavior with the inert gas unit, so I include
a report I wrote about the behavior.
Regards,
Eric

Hi Eric,
Thank you for sending along the report on the issue you are seeing with your diamond monitor. After looking through it we
have a few follow up questions (below) before making any conclusions. If it is easier and you are available for a call
next week to run through things please let us know.
- The report mentions restarting the electrometer. What are the symptoms that drive the restart? i.e.
software related crashes, or testing to see if this changes the diamond behavior
- Has anything changed in the test setup or analysis since March? Or since the diamond was first installed?
- Are all components in the inert gas purge UHP rated? Including tubing, regulator, etc.
Thank you,
Val

Valerie, all in cc,
I've found the electrometer not as stable as I would have expected. I've had to power cycle it sometimes few times a week to get
reliable signals. I don't have any error logs to report, but I'll make a table below of my observations in July.
Not very detailed, sorry.
Nothing changed since March, but some mechanical mounting. In March I changed motorized stages under it.
The BPM is always under N2 flow (High Purity Grade), and with the recommended flow.
Eric
7/13 Had to restart twice to remove large background currents of 11 uA. X-ray total current ~ 100nA.
7/19 Rebooted EM after end of experiment after noting dark currents were high.
7/23 BPM/EPICS not running. Did reset

Eric,
Attached is the IEMR report for you device. As you will see from the report the metallization of the sensor has been compromised.
Contamination in the operating environment is the suspected cause of the performance degradation.
Our recommendation is to replace the diamond and requalify the device.
Let us know how you wish to proceed.
Regards,
Matt

Hi Eric,
This mail is just to confirm what we discussed last week; i.e. we will go ahead and replace the diamond in
your device for you for the lower fee of the quoted inspection and minor repair.
We will also provide updated information advising the use of He gas and let you know about any other pertinent
points to be observed when spec’ing other parts of the gas delivery system.
Kind Regards

Thank you Rob,
you can count on me to get back to Sydor after the summer run of 2022 with any performance issue.
Helium makes sense too. I would appreciate getting an estimate of when I will get the repaired BPM back.
Happy Thanksgiving,

Last week, I received the new Sydor X-ray BPM.
It is S/N 17, and its performance is attached in att. 2.
It was shipped around March 30, and arrived on site on Friday April 1.
I got it on my return to work from vacations. |
