Optimizations on 200 kV electrostatic accelerator have been done in order to increasing ion current on target, improving vacuum condition and reduction in x-rays emission, increasing stability of high voltage power supply and reaching much greater achievable voltage value. The accelerator tube has most important effect on beam tracing in the electrostatic accelerators. So precautions most be considered in designing and constructing of this part. In order to finding permissible tolerances in construction and assembling of 200 kV electrostatic accelerator column, first the effects of angle deviation of a part from accelerator axis on beam track in the accelerator tube was simulated with Simion 7.0 computer program. We found that in order to prevent beam lost, the tolerances of balancing and co-centering of each part should be smaller than 0.1 mm. Each part of accelerator tube constructed by tolerances lower than 0.05 mm. Ultrasonic cleaning method used in pre-assembling process of parts. Because of its excellences, in the new tube we used borosilicate glass instead of high density alumina as insulators between the metallic electrodes. After three days of working vacuum pumps the system reached to 8.0×10-7 and after months to 5.0×10-7 ultimate pressure values. Measurements showed that by these considerations the maximum of reachable ion current on target was 1.1 mA which increased 50% compared to old machine, while x-ray emission intensity was increased by 25%. Optimizations of high voltage power supply are now under studies and tests

In This paper we will introduce the process of design and manufacturing an electron accelerator with 10MeV energy and 100kW power as the first Iranian powerful industrial electron accelerator. This accelerator designed based on modeling of one of the most powerful industrial accelerator called Rhodotron. But the design of the accelerator in a way that can be localize by relying on domestic industries. So although it looks like a Rhodotron accelerator structure but has some different in design and manufacture of components, the results are satisfactory

The Iranian Light Source Facility (ILSF) as a national project is a 3 GeV third generation synchrotron light source facility which provides high energy super bright X-ray for the users. Design of the ILSF storage ring emphasizes an ultra low electron beam emittance (below than 5 nm.rad), beam current of 400 mA, great brightness, stability and reliability which make it competitive in the operation years. Several lattice alternatives have been explored for the ILSF storage ring. In this paper, we present the design feature of the ILSF storage ring, give the linear and nonlinear dynamic properties of the lattice and discuss the related beam dynamics specifications

The goal of electron linear accelerator project in institute for research in fundamental sciences(IPM) is to build its components as many as they can in Iran. This accelerator is a traveling wave type. Investigations show that there are various techniques in forming and connecting the accelerating tube cavities. The shrinking method applied for constructing the accelerating tube is selected based on the one applied for Stanford University’s Mark III accelerator. With success in building an 8-cavity test tube and finding the problems of the method, the construction of the final accelerating tube with 24 cavities has been accomplished. The results show that the obtained frequency of 2996.5 MHz and quality factor of 11200, satisfy the design desired values.

The electric field in cavity accelerates charged particles and magnetic field of magnets changes the direction of these particles in cyclotrons. In order to establish the electric field inside the cavity, a noiseless radio frequency (RF) signal should be generated, amplified and sent to cavity. The resonant frequency of the cavity could be changed by temperature variation. Variation of resonant frequency will cause reflected power from the cavity. in this work the low level RF circuits with task of signal generation, phase and frequency Adjustment, cavity resonant frequency Adjustment, protection of the RF set from the reflected power and stability of RF system was designed

Up to now, different designs have been introduced for measurement beam profile accelerators. Secondary electron emission monitors (SEM) are one of these devices which have been used for this purpose. In this work, a SEM has been constructed to measure beam profile of ES-200 accelerator, a proton electrostatic accelerator which is installed at SBU. Profile grid for both planes designed with 16 wires which are insulated relative to each other. The particles with maximum energy of 200 keV and maximum current of 400 μA are stopped in copper wires. Each of the wires has an individual current-to-voltage amplifier. With a multiplexer, the analogue values are transported to an ADC. The ADCs are read out by a microcontroller and finally profile of beam shows by a user interface program

Medical electronlinear accelerators are the most practical radiotherapy facilities in cancer treatment. About 52 percent of patients are treated by these radiotherapy systems during their treatment process. However, in developing countries there are not enough systems and recent studies reported the shortage of 5000 megavoltage radiotherapy accelerators all over the world. According to international standards, there is a need of one medical linac for 180000 patients. In Iran, cancer is the third cause of death after cardiovascular diseases and accidents. This study indicates the number and status of medical electron accelerators in radiotherapy centers in Iran

It is well known that the acceptance tests should be done when a cyclotron installed in order to measure the performance claimed by manufacturer. As well as the photon and neutron dose rate during the production of flourin-18 and nitrogen-13 in self shield cyclotron in Masih Daneshvari hospital have been measured as function of distance and beam current. The first Self-shield hospital cyclotron (GE PET Trace 700) has been installed in Masih Daneshvari hospital in 2012. The yield performance of 2858.32, 138.15 and 1047.5 mCi has been measured for 18F–, 13N-13NH3 and 11C-11CO2 respectively. In flourin-18 target, the neutron dose rate observed 13.8 µSv/h at 35 µA target current at the distance of 1 m of near to the target support cabinet. With increasing of distance from 0.5 to 2.5 m near the cyclotron doors at 35 µA target current, the gamma dose rate decreases from 8.6 to 2 µSv/h in nitrogen-13 target. The measured yield for all tracers was higher than the value reported by manufacturer and the amount of shielding in GE PET Trace 700 is enough to have safe dose rate during production
