REQUIREMENT DESCRIPTION:

Under this call AFRL is seeking to develop a cryogenic refrigeration system (cryocooler). The objective is to develop a cryocooler prototype with the following desired characteristics; low jitter (less than 500mN rms, total), operate within 70-120 Kelvin, have a heat rejection of 275-325 K and deliver cooling in the range of 1-10W. The cooler must be capable of having control electronics which can be adapted to support controlled export vibration and function in a 300krad total dose radiation environment. The cooler must be scalable to support cooling loads in the indicated operating temperature range. This prototype flight demonstration unit will be delivered at the end of the contract. The use of existing cryocooler components to develop this state of the art cryocooler is an acceptable method of development.
