Abstract
A microcalorimeter radiation detector that includes a tin absorber having orientations of (420) and (311) with grain sizes greater than 100 nm. Tin absorber blanks were electroplated on a sacrificial substrate changing chemistry makeup, current density, and time to realize pure tin deposition of the desired characteristics.
Claims23
A photon absorber material, comprising:
- a tin material having a controlled preferred crystalline orientation and grain size formed through electroplating.
A microcalorimeter radiation detector, comprising:
- an absorber material consisting essentially of a tin material having a controlled preferred crystalline orientation and grain size formed through electroplating;
- and
- a sensor to which the absorber material is bonded.
A method of making an absorber, comprising:
- electroplating tin onto a sacrificial substrate;
- wherein the electroplating is performed using a selected duty cycle to form a tin material having a preferred orientation selected from the group consisting of (420) and (311) and a preferred grain size.
A method of making a microcalorimeter radiation detector comprising:
- electroplating tin at a selected current and duty cycle to produce an absorber having a preferred orientation selected from the group consisting essentially of (420) and (311) and a preferred grain size;
- and
- bonding the absorber to a sensor.
