The EIC Beamline test stand has been upgraded with 1500 W heater which is controlled via the LabVIEW software developed by DSG. The test stand has additional temperature sensors on the heater pipe to allow faster response of the controls to a change in temperature.

As of 4pm today the temperature of the inner pipe (simulated beryllium beamline) is almost at the target temperature of 100 C (see RTD_D below). Within the coming days we will complete air flow test as we did previously and show the effect of the airflow at
different locations of the inner surface of the outer pipe (simulated silicon). The test stand has aerogel covering the area of the "beryllium" beamline, which will prevent the airflow from contacting that surface directly. We expect this to change how the
flow of air reduces the heat on the surface of the simulated beryllium beamline.</div>
