March 7, 2017 - NIST has produced its first round of prototype detectors for TolTEC's 1.1mm array.

NIST has produced our first array of 1.1mm MKID detector geometries. These prototype detectors test various feature geometries as we refine the parameters that will yield the best array of 1.1mm detectors. Each circular feature with a cross inside is actually two detectors - one for each polarization of the incoming light. The feature with only a half circle is a test of the detector's sensitivity to the other polarization detector's presence.

Here is a closeup of a single pair of MKID detectors. The detection of the incoming light takes place in the horizontal and vertical bars that span the circular structure. Most of the rest of what you see is capacitance that enables the readout of the signal. This device was produced by our colleagues at NIST.

February 2, 2017 - Word came today that NVIDIA has generously donated a Titan X Pascal GPU to the UMass TolTEC group to support the development of the TolTEC analysis pipeline. We are currently investigating the benefits of moving the analysis pipeline from a CPU-based approach to a GPU-based approach. This donation will allow some of our students to get to work on a much more powerful GPU than we currently have in the lab. Many thanks to the NVIDIA GPU Grant Program.

February 1, 2017 - TolTEC is going to be big! The UMass undergraduate team working on TolTEC built a model of the footprint of the instrument and then got inside. It's a little intimidating that we all fit with lots of room to spare.

January 12, 2017 - The first major piece of TolTEC equipment has arrived at UMass - our PT415 Cryomech pulse tube cooler. We're looking forward to getting this installed in a new small Precision Cryogenics vacuum can that arrive in a few months.

December 15, 2016 - Come visit with some of the TolTEC team at the AAS meeting in Grapevine, Texas. We are having a session for people to hear about results from LMT early science and a discussion about the TolTEC surveys. Here's a flyer for the event.

December 1, 2016 - We have posted our add for a postdoc to work on TolTEC to the AAS job registry. Please let interested candidates know. This is a great opportunity to work on a fast-paced and exciting project.

October 19, 2016 - Check out the three versions of the TolTEC Project press releases: UMass, ASU, INAOE/Mexico (in Spanish!)

October 16, 2016 - We have finally downselected our logo from a bunch of great submissions. Thanks to Sean and Sam for the winning entry that includes both a nod to TolTEC culture as well as a radio telescope.

September 28, 2016 - GW - We have just completed our project-wide, two-day technical Kickoff meeting. The meeting was held at INAOE in Mexico at the LMT Project office. Most subsystems have passed PDR and the technical team is now off to the races in detailed subsystem designs. We also have had our science team kickoff meeting with over 40 people in attendance. Everyone is encouraged to sign up for our email news letters on the Get Involved section of this website.

Several members of the technical team working on TolTEC

September 9, 2016 - GW - It is finally official, TolTEC has been funded by the NSF.

October 16, 2015 - GW - We've got a project public website.
