BN Basu

It is always a pleasure to write something for Vacuum Electronic Devices and Application Society, India. I do not intend to list the vacuum electron devices developed by the various organisations in the country nor enumerate the achievements of these organisations. I would like to present some points in my own perspective. I am likely to miss many a point and fail to mention the names of significant ‘contributors’. For such inadvertent lapses I may please be pardoned. VEDAS is not responsible for the facts and opinions presented here by me.
