MANCHESTER UNIVERSITY/COCKCROFT INSTITUTE , England, from 1 st June 2006. My major work at Cockcroft Institute is design the Beam Delivery System for ILC.
ACCEL Instruments GmbH , Bergisch Gladbach, Germany, from 1 st February 2005 to 1 st August 2005. My major work at ACCEL was commissioning and optimize proton beam for proton therapy cyclotron (PROSCAN) at Paul Scherrer Institut (PSI), Switzerland.
GRONINGEN UNIVERSITY – Kernfysisch Versneller Instituut (KVI) , The Netherlands, from 1 st November 2001 to 1 st November 2003. My major work at KVI was to design the low energy beam line from the ion source to the superconducting KVI cyclotron (AGOR).
UPPSALA UNIVERSITY – THE SVEDBERG LABORATORY (TSL) , Sweden, from 16 th March to 31 st August 2001. My major work at TSL was to design the spiral inflector and central region of the TSL cyclotron.
WARSAW UNIVERSITY – HEAVY ION LABORATORY , Poland, from 1 st May to 1 st August 2000. My major work at Warsaw University was to design the spiral inflector and central region of the Warsaw University AVF cyclotron. During my stay at Warsaw University I studied the following subject: 1 – radio frequency system of the University of Warsaw AVF cyclotron.
RIKEN - The Institute of Physical and Chemical Research , Japan , from March 1997 to March 1998. My major work at RIKEN was to modify the design of a spiral inflector and also a central region of the RIKEN AVF cyclotron. During my stay at RIKEN I studied the following subjects:
- design of the transport elements from the ECR ion source to the AVF RIKEN cyclotron,
- design of the superconducting sector magnet,
- design of the injection and extraction system for the superconducting ring cyclotron,
- design of the lattice of the storage ring.
“VINCA” Institute of Nuclear Sciences , My MSc. degree work dealt with the study of the radioactive isotopes produced and stopped in heavy targets bombarded by heavy ions at about 18 MeV/n. MSc. thesis: “Nuclear isomers produced and stopped in a thin 197Au target effected by 74Ge at 18.8 MeV/n”. My Ph.D. degree work dealt with design of the axial injection system with the spiral inflector and design of the central region of the VINCY cyclotron. Ph.D. thesis: “Axial injection and electrodes of the central region of the VINCY cyclotron”.
My main research topics are beam optics and dynamics of the ions in the injection/extraction system and during acceleration. Numerical calculations of charged particle trajectories through electric and magnetic fields are essential for this kind of research.
COMPUTER CODES:
I have experience with the VMS, UNIX/LINUX operating systems, FORTRAN and C/C++ programming languages and with the following computer codes:
- RELAX3D, OPERA-3D – programs for numerical calculation of electric (RELAX3D) and both, electric and magnetic (OPERA-3D) fields in the three dimensions
- MAD, DIMAD, TRANSPORT, GIOS, COSY - programs for tracking charged particles through electric and magnetic fields,
- ZGOUBI - program for combined spin tracking and ray-tracing of charged particles through electric and magnetic fields,
- GENSPEO – program for the investigation of the characteristics of magnetic field in one plane,
- CASINO, CYCLONE – programs for numerical calculations of the ion trajectory in a cyclotron.
