MICE Absorber Test Cryostat Plan-II

This document outlines the plans for MICE Absorber Test Cryostats, detailing the various pressure tests conducted at room temperature (R.T.) and at 20K using different dummy windows. It includes specifications for cooling tests with gas helium and liquid hydrogen, calibration procedures for thermometers and level sensors with a cryocooler, and the necessary steps to fix the design details of absorbers and cryostats at KEK and RAL. A comprehensive overview of test items is provided to ensure a successful execution of the proposed tests.
