✦ Synopsis

A robust bolometer employing a tin element at its superconductive transition will be described. The instrument is designed to respond to infra-red radiation chopped at 10 Hz and the signal is amplified, by a special transformer operating in liquid helium, prior to electronic amplification and recording. A comparison of its performance with that of a pneumatic detector will be described.

A spectrometer, designed for the far infra-red (beyond 50p), has been constructed and used in conjunction with the bolometer.
