[BNC-all] BNC E-news for the week of September 7th

[Anthrop, Heather L]

New Process Meetings

We have the great benefit of having many new users coming to work with us here at Birck, both in the labs and the cleanroom.  For those working in the cleanroom please remember to schedule your new user process meeting through Kenny Schwartz, kfschwar at purdue.edu<mailto:kfschwar at purdue.edu>.  Because of the number of new users it may take a few extra days to schedule your meetings.

Valuables

Just a reminder that the Birck Nanotechnology Center building is an open campus building, with many people working and visiting here on a daily basis.  Please remember to lock your valuables in a safe place when you leave them unattended.

VB6

Good news- the VB6 is now in a bakeout. Andrew Dean and Alan Schroeder were able to isolate the leak to ion pump 4 and it's fixtures. A new ion pump has been installed. It was able to pump down to previous good readings. It is now in a bakeout. After the bakout, the gun will have to be run up to 50kV and stabilize, then run up to 100kV and stabilize. The gun alignment will need to be done and new databases made. We are probably looking at the middle to end of next week and the VB6 will be ready for use.
Many thanks for your patience while the problems of the pattern generator board, 24V power supply, and vacuum leak was tracked down and fixed. I will give you further updates as we move along in bringing the system back up.
It has been a team effort from Raith (Vistec) with John Reilly, Alan Schroeder, Chris Gee and Andrew Dean staying on top of the machine until all the issues were resolved. Many thanks go out to them.

Best Regards,

Bill

PM Shut Down Notice 10.19 - 10.23

The Birck Nanotechnology Center will be undergoing a semi-annual preventive maintenance and service shutdown October 19 through October 23, 2015. Air handling systems, exhaust systems, toxic gas delivery, and monitoring systems will be down beginning at 7 a.m. Monday, October 19 through 4 p.m. Friday, October 23. The BNC staff will be performing appropriate preventive maintenance on the process equipment at this time as well.

All CLEANROOM research work will be suspended until the maintenance activities are completed and all systems are returned to normal. No one will be allowed to enter the cleanroom during this time period.

In addition, the laboratory areas will also be affected by this systems maintenance. As such, all LABORATORY activities that involve exhausted hoods, vacuum systems, and/or
toxic gas systems will be down beginning 7 a.m. Monday, October 19 through 4 p.m. Friday, October 23. However, work that involves taking standard electrical measurements
may be carried out in the LABS provided that fluctuating air temperature and humidity do not affect the readings. No chemical work will be allowed during this period.

It is anticipated that the building and process tool maintenance will be completed by the end of the day on Friday, October 23. Please check Coral for equipment status and
availability.

For long term research planning please refer the following future dates for our future preventive maintenance shutdowns.

Spring PM: May 2, 2016 Fall PM Oct 17, 2016
Spring PM: May 1, 2017 Fall PM Oct 16, 2017
