We propose to study the spectral energy distribution of the infrared emission from shock induced heating of dust in the Tycho supernova remnant. By compairing the IR emission from grains downstream of a shock front with the local heating rate we expect to be able to determine the characteristic size of the grains as a function of downstream position. By detailed mapping of two active regions of the shock front and a scan across the center of the remnant we should be able to determine dust properties both upstream and downstream of a shock wave. By looking at many different continuum bands we hope to be able to investigate different grain sizes and thereby determine grain destruction mechanismes and timescales.
