I’ve had the opportunity to work with many excellent undergraduate students in Michael Niemack’s lab here at Cornell.

Willow Martin (2019 – Present)

Willow is working on designing and constructing a platform for an FTS to measure optical properties of materials and coatings in our lab within our cryogenic filter wheel system. She is also involved with running cooldowns of our cryogenic testbed.

Jesse Smith (2018 – 2019)

Jesse was involved in developing new circuit boards and wiring for our dilution refrigerator, building cables for cryogenic feedthroughs, running cooldowns and working with cryogenic systems, and testing superconducting detectors.

Noah Sailer (2017 – 2019)

Noah designed a cryogenic filter wheel system for use with an FTS to measure optical properties of materials and coatings in our lab. He was also involved with running cooldowns of our cryogenic testbed and calibrating Cernox thermometers, as well as working with data from ACT to search for FRBs. Noah is now a physics graduate student at UC Berkeley.

Trey Driskell (2018 – 2019)

Trey worked with BoloCalc to adapt the sensitivity calculator for CCAT-prime. Trey also worked on developing a CCAT-prime site monitoring camera to observe the Cerro Chajnantor site in the Atacama desert.

Dallin Richards (2018 – 2019)

Dallin worked with magnetic shielding, including making magnetic shielding factor measurements, building a degausser, making measurements of SQUIDs in magnetic fields, and learning about cryogenic systems.

Michael Jack (2018-2019)

Michael was a Summer Research for Community College Students (SRCCS) student who worked on 3D printing models of the ACT and SO telescopes, testing cryogenic systems, and making measurements with our Fourier transform spectrometer (FTS).

Kaiwen Zheng (2016 – 2018)

Kaiwen’s work included learning SolidWorks and designing parts for our lab, testing and modeling magnetic shields using Maxwell, characterizing our Helmholtz coils, and testing SQUIDs and TESes in our dilution refrigerator (E.M. Vavagiakis, S.W. Henderson, K. Zheng et al., Magnetic Sensitivity of AlMn TESes and Shielding Considerations for Next-Generation CMB Surveys, JLTP 2018). She worked on running cooldowns and calibrating Cernox thermometers in our cryogenic testbed, which she also helped to construct. She wrote python scripts for data acquisition and analysis, including temperature and pressure monitoring and detector readout. Kaiwen is now a physics graduate student at Princeton University.

Tracy Paltoo (Summer 2016)

Tracy, a physics major at Adelphi University, was a Louis Stokes Alliance for Minority Participation (LSAMP) summer 2016 REU scholar. She learned SolidWorks and designed two sets of mumetal magnetic shields for our cryostats.

Kristine Lister (Spring 2016)

Kristine’s work included using Altium to design a printed circuit board for use in MUX screening. Kristine is now an Operations Research and Information Engineer.

Prabudhya Bhattacharyya (2015 – 2016)

Pra’s work included learning SolidWorks and designing and modeling parts and equipment for our lab. He designed and constructed a frame for a cryogenic test bed from Minitec components and custom parts. He also helped design and build a set of Helmholtz coils which are currently being used in our lab for detector magnetic sensitivity testing. Pra is now a physics graduate student at UC Berkeley.
