Particle Accelerator Physics and Engineering

Leader:

I.N. Meshkov
G.D. Shirkov

Scientific Programme:
Design and optimization of the operation mode of the storage rings equipped with electron cooling systems, ion sources and transportation channels for ITEP, RIKEN, NIRS, FZJ and JINR. Design and manufacturing of cryogenic system elements for JINR and CERN.
Design and construction of the low-energy positron/electron storage ring LEPTA (Low Energy Particle Toroidal Accumulator).

- Test of the prototype electron gun for the electron cooling system of the MUSES accelerator complex (RIKEN).
- Conceptual project of the system of "single-particle electron cooling".
- Computer code library for simulation of electron cooling and accumulation of charged heavy particle.
- Design of the conceptual project of the electron cooling system for the Nuclotron.
- Completing of the project stage of TWAC (ITEP).
- Proposal on beam intensity increase at COSY (FZJ).
- Nuclotron (JINR) in experiments with internal and external targets.
Design of the prototype optical monitor of the proton beam intensity.
Theoretical and experimental investigation on ion sources:
- Calculation and design of ion source elements and transportation channels.
- Elaboration of the solid material loader device to the ECR source by the laser.
- Design of the ion source X-ray diagnostics.
- Development of the program for simulation of the process in ion sources.
Design and construction of LEPTA:
- Assembly of the LEPTA ring and the first experiments with a circulating electron beam.
