Abstract for JLAB Technical Note 03-017  

Beam-induced density change (`boiling') was studied in the Jefferson Lab Hall A cryotarget using the machined `cigar-tube' target cells. Luminosity monitors were used to study both the reduction in the average target luminosity, and the onset of non-statistical fluctuations in the luminosity, as a function of beam current, raster size, fan speed, beam spot size, for both lH2 and lD2. New information on the characteristic time scale of the fluctuations was obtained.
