The ASPE!CT project (Adaptable Spectrometer Enabled by Cryogenic Technology) is developing a commercially viable, cryogenic platform addressed to a wide range of cryogenic sensors. The cryogen-free, adiabatic demagnetization refrigerator is specially designed for use with cryogenic detectors at sub-Kelvin temperatures. The project pushes the technology into the realm of reliable, compact, touch-button devices. The prototype detector stage is designed to operate with a specially developed cryogenic sensor (e.g. Magnetic Penetration Thermometer) which will be optimized to achieve a resolution of about 10 eV at the energies range typically created in kaonic atoms experiments (~10keV). The mid-term target is to lower the temperature range and to introduce continuous, high-power, low-temperature cooling, to bring a high-resolution cryogenic spectrometer system to the market. Later stages of the project should see an optimized experimental set-up performing high-resolution kaon-mass measurements in a beam to be provided by the J-PARC (Tokai, Japan) or DAΦNE (Frascati, Italy)
