Dear Colleagues,
you find attached a first draft of the slides I'm going to show at the 
DOE workshop next week. The talk is 30' + 5'.

Slides are not in the final form - but already in a quite definite 
shape, so that I can circulate them to you to receive feedback and comments.

Note that slides n. 5 is missing, as well as slide n. 29. Conclusions 
still needs to be written properly.

Other than your general comments, I'd like to hear the following:

* Eder, Gordan: my idea about slide n.5 was to present BDX as a "second 
generation" dump experiment, dedicated to LDM, after the experiences 
from E137 and others. Also, I'd like to compare with proton beam-dump 
experiments (LSND, Miniboone), underlying the complementary (protons: 
maybe higher production, but higher beam-related backgrounds. Electrons: 
beam-related backgrounds are lower). Do you think this is reasonable?

* Eder, Gordan: can you please have a look at the reach plot (slide 
n.24)? These were taken from proposal, but I do not know if any MAJOR 
change in limits from other experiments should be added

* Marco, Elton: slides n. 28 and 29 shows the current experiment status 
and future plans. In slide n. 29 I can show that a realistic cost 
estimate for facilities (and partially for the detector) has been 
carried out. What's your opinion about? Is it worth to discuss or it is 
better to put in the backup?

* All: do you think it is better to circulate the slides to people at 
JLab? At the moment, in particular for the mu pipe test, I am just 
saying that the plans have been "discussed" with the management. If we 
want to stress this more (like saying that the plans have been 
pre-approved, or something like this) then we need to.

I expect to receive your feedback within Friday morning (Europe time), 
so that I can work on this on Friday, circulate again on Friday evening 
(Europe time), and if necessary circulate to people at JLab.

Bests,

Andrea
