24.06.2021: New chamber for the QTZ user facility “Ion Traps” under vacuum

The new apparatus to be used in the user facility “Ion Traps” has been assembled and put under vacuum. Did we forget to attach a flange??

No, we didn’t. ;-) In fact, it was exciting to activate the roughing pump for the first time and watch the pressure drop from atmosphere below E-1 mbar. However, we were expecting to even reach the low E-2 mbar regime. First tests revealed a leaky leak in the main chamber. After having that fixed, the turbo pump was activated. The pressure went down to the low E-6 mbar regime after 1,5 hours of pumping. Further leak tests are now pending.
