The Large Aperture Telescope (LAT) receiver engineering group has developed a first thermal model of the 50 K radiation shield. Due to the large receiver size this sub-component is challenging to design. The shield supports the alumina IR filters which need to be sufficiently cooled. Several options are currently being investigated to reduce thermal gradients, e.g. improved heat straps or higher conductivity materials. The figures below show the thermal model of the LAT receiver cryostat.
Key Dates and Upcoming Activities
The project and collaboration have recently completed the Analysis of Alternatives. This allows us to refocus the project to developing a new project baseline for future reviews. We presented our strong and further strengthened science case to the P5 Particle Physics Project Prioritization Panel.
