[Dsg-eic_tracker] EIC beam line test stand flow test

[Brian Eng]

Quick and dirty plots from Excel, which is kind of a pain/slow to change plot settings with a file of this size.

I'll send a summary table shortly. On quick glance the beampipe temperature is maintained better with the aerogel than without it, but still maybe not good enough.

Marc,

Could you take another run and log from startup (room temp) to steady state then flow 10 and 25?

marc,
make the plot from 1200 onwards i.e. for flow 150 -250 lpm
it appears that at these  flow rates the temperature of RTD C is around  27 C

Hi Patrizia and Rolf,

The flow tests are complete. The beam line pipe was heated to ~100C and air was flowed at 10, 20, 50, 100, 150, 200, and 250 liters per minute. Each flow test ran for 3 hours. After each test the controls waited for 3 hours to allow monitored temperatures to recover to approximately the same starting temperature for every test.

Sensor locations:

RTD_A, B, and C - inner surface of outer pipe (silicon)

RTD_D - outer surface of inner pipe (beryllium beam pipe)

RTD_H1, and H2 - outer surface of the heated pipe (for controls)

Brian,

The full data log is located at O:\DSG\EIC\Software\LabVIEW\Teststand_data\0502_0504_flowtest.xlsx<file:///O:\DSG\EIC\Software\LabVIEW\Teststand_data\0502_0504_flowtest.xlsx>


Regards,
Marc
