摘要：

We present the mechanical device used to install the Raft Tower Modules (RTMs) into the cryostat of the camera for the Large Synoptic Survey Telescope (LSST). In an RTM, the charge-coupled devices (CCDs) are packaged into a 3 x 3 Raft Sensor Assembly (RSA) and coupled to a Raft Electronics Crate (REC). An RTM weighs 10 kg, is roughly 500 mm tall, and has a 126.5 mm-square footprint at the CCDs. The grid array which supports the RTM in the cryostat has a center-to-center distance of 127 mm. One of the key challenges for installing the RTMs is the 500 mu m gap between CCDs of adjacent modules contact between adjacent CCDs is strictly forbidden.
