[Dsg-eic_tracker] EIC simulated beam line flow tests

[Marc Mcmullen]

Hi Patrizia and Rolf,

After discussing the matter with the EHS group (fire protection engineer, industrial hygiene, and pressure systems design authority), we determined that we could safely run the test stand at a higher temperature as long as we keep the safety interlock set well below the auto-ignition temperature of the mineral oil (300 C).

We increased the temperature of the test stand to around 210 C and made adjustments to the airflow to reach 100 C (RTD_D) on the beam pipe while cooling the inner surface of the outer pipe (silicon region) to ~30 C (RTD_A, B, and C).

Attached is the plot from yesterday's test. It looks like setting to heater to 210 C, with a flow of about 212 - 215 Lpm gets us right to those temperatures.


Have a great weekend,
Marc
