Belle DUT, intcal
HV=80V, 31.8 MHz, beam off
1 sample, transparent mode
cooling
chiller set to 13 deg.

Since there was no (or to less) water flow through the small pipe of the origami module, all previous runs with cooling must be repeated.

Bypass removed to achieve better watter flow at the module!
Chiller pump is set to 2800 rpm
