Final Intern Update

We're wrapping up our summer jobs at CCLDAS. We would like to thank Andrew,  Mihaly, Anthony, Paige, Anna, Evan, Addie, Tobin, Mark, Keith, Chris, and Spenser. This experience was truly invaluable and we all learned a lot.

Our last week at the lab was busy, as always. We began by helping install the UHV chamber in the beamline. First, we disconnected LEIL from the beamline and moved it aside. Next, we moved the UHV chamber into place, only to realize that the wheels  put the chamber too high. We eventually removed the wheels from the UHV assembly  in order to lower it to the correct height. The chamber is now properly in place and is currently in use for Andrew's neutral gas generation experiment.  In the process of installing the new chamber, we learned tons about high vacuum systems. Andrew taught us about flange installation techniques, cryogenic pumping, chamber alignment, and more.  Look below to see  pictures of the installed UHV assembly!

To our chagrin, the dust particles never hit the target, suggesting a misalignment. However, after disassembling the beamline, we were able to determine that the alignment was actually correct. This has brought about many concerns for Andrew's experiment. 

After the UHV was installed, we wrote a Matlab program for Paige. This program can be used to find peaks in the charge values recorded by the LeCroy oscilloscope for the Dust Coordinate Sensor, ultimately allowing us to determine a dust particle's position as it travels down the beamline. 

We then made a program for Spenser's Database project, which provides an organizational platform for data taken for various accelerator experiments. Our program puts LeCroy waveforms into a LabView friendly format  and posts them to the CCLDAS database. 

As a bittersweet ending to the week, we had to say goodbye to our fellow high schoolers from the lunar rover LEGO®  Mindstorms camp. They brought youthful energy to our workspace, and we will miss them as they continue on their journeys in high school.  Check out their awesome Lunar rovers in action below!

We all enjoyed our time at the lab. Thanks again to everyone at CCLDAS!

Thanks!!!
