HIFI: CASCA07 – lunch meeting 6 June, Polarisation studies with Herschel/HIFI Team lead by M. Harwit (mission scientist), including M. Houde, W. Jellema, G. Melnick, K. Menten, and D. Neufeld Initial program will concentrate on masers –Potential for high linear polarisation levels –Many spectral lines (i.e., water) predicted If successful, expand to other types of observing programs Recruiting graduate student  talk to me!
