Prototyping of LST (beginning of 2013)
Slide7Resources-I
PP budget will support a part of the following actions
Testing CFRP elements (Only critical elements)
Design by MERO (2nd / 3rd iteration)
FPI development of PM with Hamamatsu
Missing significant part of prototyping
Individual groups must look for the resources
Slide8Resources-II
Problem: We can not enjoy the cost reduction in the mass-production. Everything must be very close to the market price. No big discount from industries.
Rough estimation by M.T.
(Total LST Proto project may cost about 8-9MEuro)

Slide9Resources-III
We need to define the specification/requirements and design of LST
asap
, and then estimate the cost for
for development (
PMTs
,
Mirrros
, CFPR tubes, electronics, etc.)
for Prototyping (the first telescope)
for Mass production (7 more telescopes)
For examples, offers for 3000PMTs and 150,000PMTs are quite different
Slide10Critical Path
We need the dedicated MC for LST
For the optimization of F/D and FOV
Structure will require
F/D = 1.2, FOV=4 degrees, 2ton cameras
If the requirements exceed these numbers, the current design will experience the significant change/modification
Slide11Risks
I do not see any significant risks at a moment, but we need to list up all possible risks at least before starting prototyping.
Slide12Cost estimate
It is now on-going by T.S. and O.B.. They will deliver us reliable numbers with our best knowledge.
We need three costs
Cost for developments/prototyping elements
Cost for prototyping LST
Cost in the construction phase (mass production)
