2  Background on AMiBA  Problems/Things to Consider  Solutions/introduce my project  Fabrication  Conclusion  Acknowledgments 2

3  What is AMiBA?  How does AMiBA collect data? 3

4 4

5 5 Vacuum cold head Receiver

6  vacuum not perfect  Too Much Down Time  Cold Heads turn on using a local switch  AMiBA is expanding from 7 to 13 elements 6

7  Install a remote control › ADAM Controller  Controls cold heads through Ethernet connection  Build a new and bigger split box to house 13 switches 7

20  Increase in efficiency of controlling cold heads  Reduction in down time for the AMiBA team  Smoother transition towards expansion of AMiBA  Personal gain: real engineering and Tech experience with the design and fabrication of split box 20

21 I would like to thank my mentor and collaborators: Derek Kubo, Pablo Altamirano, Peter Oshiro, and John Chen. Everyone at AMiBA and SMA for the use of facilities, materials and tools. The rest of the Akamai interns for support, help, and friendship. Lastly Sarah Anderson, Lynne Raschke, Lisa Hunter, Hilary O’Bryan, Scott Seagroves, as well as the entire CfAO Mahalo to everyone! Funding provided through the Center for Adaptive Optics, a National Science Foundation Science and Technology Center (STC), AST
