Bolometer Technology I 6.1 Pixel Thermal Design

2. Bolometer Technology I 6.1 Pixel Thermal Design. SCUBA-2 Pixel Thermal Design. Can we design a pixel that meets a number of constraints and satisfies certain design criteria? We have constructed a model that allows us to optimise various parameters in an attempt to answer this.

4.2 Cryogenic Design

2. 4.2 Cryogenic Design. Requirements. Array temperature: Needs to be in the 100mK regime - Engineering margin on achieving background limited NEPs for large numbers of pixels - Power handling requirements. Optics/filters: Need to be a cold as is practical
