Title:
カロリーメータ
Document Type and Number:
Japanese Patent JP4646441
Kind Code:
B2
Abstract:
The present invention is intended to provide a calorimeter for converting a quite small amount of heat into an electrical signal, especially a radiation detector providing improved energy resolution and count rate, by using a superconducting transition edge. The calorimeter has an absorber for absorbing radiation and producing heat. This absorber is formed on a resistor whose resistance value is varied by the heat. The resistor is formed on a membrane that controls escape of the heat. The calorimeter is characterized in that it is further fitted with a heat dissipation device for letting active electrons produced in the calorimeter escape to the outside.
