Feasibility Study forFeasibility Study forMass-Production Mass-Production (not official)(not official)

to Improve Productivity of 20 inch PMT

1. Simple Structure for easy production 2. Unique Facilities for better efficiency

Early –Stage Estimation100K tubes in 5 years (20K tubes per year)Number of Employees : 50 peoplesPMT Price : $2,000

We are checking whether glass bulbs can be supplied from glass venders without big problems or not.

Next Step of Large Format HPDNext Step of Large Format HPD

1. 13 inch HPD is being developed with collaboration of the Univ. of Tokyo and JST(JAPAN SCIENCE AND TECHNOLOGY AGENCY).

2. Working prototype would be made in 2 years (by mar.2007).

3. Development will be finished by Mar.2010.
