A photonuclear method with the use of high-energy bremsstrahlung (Eg>8 MeV) of high intensity (>= 1004 W/cm2) provides a possibility of the ecologically safe production of a number of isotopes for nuclear medicine. The conditions of generation of the radiation field having such characteristics as well as the features of photonuclear production of W-181,Pd-103, Cu-67 and other radionuclides are considered in the report. At the initial stage the study of the isotope production is performed by means of the computer simulation in a simplified 2D geometry of the Linac output devices. The code on the base of the PENELOPE/2001 program system supplemented with the data on the excitation functions of the corresponding reactions was developed. The dependences of the isotope yield (gross and specific activity) on the electron energy (30…45 MeV), as well as, the data on absorbed energy of radiation in the targets of natural composition are represented. The experimental results confirm the data of modelling. Main trends of realization of the photonuclear method for isotope production and the necessary conditions of the increase of its yield are analysed.

One of TRIUMF's isotope production facilities, the 2C Solid Target Facility (STF), is being upgraded. This installation is located on a primary beamline of TRIUMF's 500 MeV Cyclotron. As a part of this upgrade project, the STF Control System is also being revised. Changes to the STF are meant to enhance reliability and maintainability. The existing STF controls have run very reliably and have provided the required functionality but were implemented in part using different technology to that used for the majority of the cyclotron's Central Control System. The new hardware and software controls should provide a simpler, more easily maintained configuration. Additional goals are to modify the user interface to more closely resemble the interface used for running the 500 MeV Cyclotron, to enhance the event annunciation, and to increase the number of parameters logged.
