27 May 2015 | | Abstract: | We have systematically investigated the energy resolution of a magnetic
micro-calorimeter (MMC) for atomic and molecular projectiles at impact energies
ranging from $Eapprox13$ to 150~keV. For atoms we obtained absolute energy
resolutions down to $Delta E approx 120$~eV and relative energy resolutions
down to $Delta E/Eapprox10^{-3}$. We also studied in detail the MMC
energy-response function to molecular projectiles of up to mass 56~u. We have
demonstrated the capability of identifying neutral fragmentation products of
these molecules by calorimetric mass spectrometry. We have modeled the MMC
energy-response function for molecular projectiles and conclude that
backscattering is the dominant source of the energy spread at the impact
energies investigated. We have successfully demonstrated the use of a detector
absorber coating to suppress such spreads. We briefly outline the use of MMC
detectors in experiments on gas-phase collision reactions with neutral
products. Our findings are of general interest for mass spectrometric
techniques, particularly for those desiring to make neutral-particle mass
measurements. | | Source: | arXiv, 1505.7222 | | Services: | Forum | Review | PDF | Favorites | |
