    Team Toco finished closing up the new low-frequency array with the magnetic shield (left pic). Now LF (30/40 GHz), MF (90/150 GHz) and HF (150/220 GHz) are all together! (Right pic) all the Cryo shells are also back!! , almost time to cool down

    ... and there we go! The newest low-frequency array was installed in the optics tube. Almost time to close the cryostat up. Pic by

    The low-frequency array made it safely to the site. Yaqiong and Steve are checking that everything looks nominal. for when it gets mounted on the optic tube!

    The mid-frequency array (PA6) 90/150 GHz array today was taken off. for pics of LF! The other two grey cylinders contain PA4 (150/200 GHz) and PA5 (90/150GHz).

    The team is making space for the new low-frequency array! Today the magnetic shielding and the amplifiers were removed. In the next couple of days, the mid-frequency array and the lenses will be removed as well

    The final Advanced ACTPol upgrade is underway! Today we extracted the almost 1 ton receiver from the telescope to install our new detector array, and enable new measurements of the oldest light in the Universe.

    What are you doing on Thursday night? If you're an ACT grad student at Princeton you're probably putting an array and filters into the DR!
