30 years operation of 25 MeV proton linac I-2 in ITEP at beam current of 200-230 mA

The first in Russia strong-focusing 25 MeV proton linac-injector I-2, computations, design and construction of which have been carried out under the guidance of Prof. I.M.Kapchinsky, will celebrate this autumn its 30-th anniversary. Output current of the beam at energy of 25 MeV year after year is 200-230 mA, down time is less than 0.5% of schedule time of about 5000 hour/year. Launched a decade before RFQ epoch coming the linac I-2 is the ''living witness'' of its physical project adequation to requirements of beam dynamics and adhere to assigned stringent tolerances that determines so long machine life.
