AMS of Ho-163/Ho-166m at DREAMS facility (HZDR)

Development of AMS at DREAMS for experimental determination of the ratio 163Ho/166mHo in ECHo samples. The long-lived 166mHo is an unwanted by-product of the 163Ho production, which is reduced to ultra-low levels (10-9) after sophisticated mass separation. For a background-free measurement of the 163Ho spectrum in the ECHo metallic magnetic calorimeters the absence of 166mHo is critical. DREAMS website
