Sujet:	Search for neutrino oscillations with CHORUS 

Par:	Dr. Juergen Brunner, CERN

Resume:	A short introduction will be given into the phenomenology 
	of neutrino oscillations and the motivation to search for 
	it at accelerators.
	The CHORUS detector was completed on schedule in April 1994.
	Its design and performance will be described.
	Physics data taking was conducted from May till October 1994
	and from May till October 1995 at the refurbished SPS neutrino
	beam at CERN. 2*10^19 protons on target were delivered and 
	about 400,000 neutrino interactions in the emulsion target were 
	recorded on tape. The present status of the analysis of these 
	data will be discussed.
	At the end of the 1995 run the emulsion target was removed and
	developed. The status of the emulsion scanning and schedules
	for the next future will be described.
