Machine-related backgrounds are likely to be high during the first year of 
Babar running.  It is prudent to plan for somewhere between 5-10 times 
more than the nominal background that we anticipated in the TDR.  

The need for someone to coordinate such a plan was discussed at the last 
Technical Board Meeting.   Babar Management has created  the position of 
Background Remediation Coordinator (BRC) to deal with this.  I am most 
pleased to announce that Guy Wormser has enthusiastically accepted this 
post.  Guy will naturally work very closely with a) the Mattison 
Background group (and in particular with Teri Geld's Monte Carlo effort), 
b) with the Physics Coordinators, with the Run Coordinators, and c) with 
the System Managers.  The general areas of concern for the BRC will be:

	1) Helping to update the TDR occupancy and radiation dose tables 

	2) Coordinating the Systems (including the trigger and dataflow) 
to study in detail 
	the impact of the backgrounds on their hardware, and if needed to 
develop solutions to 
	remediate the impact

	3) Coordinating the Systems and reconstruction folks to study in 
detail the impact 
	of the backgrounds on the system software algorithms, and if 
needed to develop 
	work-arounds which minimize the deterioration of system performance

	4) Helping the Physics Coordinators to study and develop 
remediation techniques
 	for particular physics channels

	5) Help the Systems to evolve the resources and capabilities to 
provide active feedback and 
	detection of machine-related backgrounds in the post April 99 era, 
so 	that Babar becomes
	 an adequate replacement for the present suite of background 
detectors.  To develop with 
	Tom Mattison, in coordination with the Operations Group, a system 
of liaisons who will 
	have a 24-hour presence in the machine 	control room. 

Please give Guy the support he will need to make this aspect of our 
program a major success.  Please forward this note to your colleagues who 
should be made aware of Guy's new role.
