Hello,
there is a factor between Setpoint Speed and real Speed of our spinner.
A Portable Laser Speed-Monitor is in the drawer under the spinner in P8.2.22
in case if
someone wants to measure.
This spinner will soon get replaced.
After the replacement
*all saved recipes/programs will be gone
*the speed will be slower and stay at the setpoint.
If there is anything you still need from the old spinner, now is the time
to access it.
Best regards
Bastian Aisenbrey

Betreff: Important Notice: Upcoming Ventilation and Pressure Control Tests
in the Cleanroom
Dear colleagues,
I have just received the following information regarding upcoming tests
related to the pressure control system in the cleanroom and the optics labs.
Please take note of the planned activities:
Friday, 29 November 2025, between 8:00-10:00
Short shutdowns of the control system in several cleanroom areas (approx. 5
zones).
Each zone will be switched off for around 2 minutes.
Monday, 8 December 2025 (during the day)
Closure of the fresh air for the Optics Laboratory levels (2nd and 3rd
floors).
This means no supply or exhaust air will be available-only recirculation
will remain active.
The duration is expected to be 2-4 hours.
Please be aware that no work with chemicals should be carried out during
these times, particularly on 8 December, as there will be no air exchange in
the affected areas.
Thank you for taking this into account and adjusting your schedules
accordingly.
Best regards,
Christof
Dr.
