  • A character driver of amplifier for the RF-generator 77.78 MHz at cyclotron DECY-13 in Yogyakarta

    International Journal of Power Electronics and Drive Systems, 2024
    Measurement of power supply for design of experimental cyclotron in Yogyakarta (DECY-13), i.e. RF-generator 77.78 MHz, especially driver amplifier as important part, has been carried out, in order to minimize the reflected power. Starting from direct digital synthesizer (DDS) as exciter of the radio frequency (RF) wave, having power up to 20 W, the signal sent then to the driver, that has an amplifying factor of around 50. Output of driver works as input for final power of designed DECY-13, which needs about 10 kW of RF power supply for operating the cyclotron. Using network analyzer to get the best position of the RF-power-coupler, it was found the value of dee impedance equals to (50.9 - j0.3) Ω. The signal detected has the behavior as capacitively having value of around 6 nF, that showed by smith chart. An output of 0.8 W by DDS has resulted of 300W to the driver. By a pure resistance 50 Ω dummy load, the system can achieve final power of almost 10 kW.

    The dee voltage is one of the key parameters to identify the cyclotron RF system specification. However, direct measurement of dee voltage is difficult to do, due to high voltage and the introduction of measuring devices could interfere with local EM field, leading to disturbance of the impedance of the system. Therefore, the dee voltage measurement which is done indirectly by modeling the cavity as a lumped RLC circuit model and calculating the voltage at the lumped RLC circuit is proposed. The RLC equation in the lumped circuit model could be obtained by solving two coupled and transformed equations of the lumped RLC circuit model in frequency domain. The equations consider the inductance values of the coupler. The equation is carried out using Fourier transformation resulting in the RLC equation of the cavity. Through the RLC equation, the RLC value could be obtained by substituting the equation for several values of frequency. To check the consistency of the method, results obtained from the real part of impedance only and from the imaginary part of the impedance only are compared.
  • The Effect of Technical Operational Parameter on the Performance Stability of RF-Power Transfer for Cyclotron DECY-13 in Yogyakarta

    Journal of Physics Conference Series, 2024
    Radio Frequency (RF) power transfer needs special condition in order to achieve high transmission coefficient, the matching condition between source and load must be met. In this case there are 3 important technical operation parameters, namely conductivity of cooling water, vacuum pressure, and magnetic field. They have influence on the impedance of the RF-generator load. An RF-generator of the frequency of 77.76 MHz having power up to 10 kW has been used in the construction of self-built cyclotron DECY-13 by BRIN in Yogyakarta. The experiment showed the increasing of power reflectivity up to 61% by rising of water conductivity 16%, i.e. 0.97 µS/cm, that used for cooling of the entire system inside the cyclotron chamber. The results also showed that the homogeneity of magnetic field from 1,5 to 2,0 ppm has changed the detected of impedance to be ~10 Ω at its real part and ~5 Ω at its imaginary part, by using network analyser based on Schmidt Chart analysis. On the other hand, the effect of vacuum pressure starting at 10−3 mbar to high vacuum have no significant effect on its real and imaginary parts of impedance.

    A convolutional neural network model to solve some quantities of two dimensional axially symmetric eigenmode simulations used for particle accelerators is proposed. The model is trained using simulated data using SUPERFISH eigenmode solver. The input is a randomly varied pillbox cavity image that is down-converted using first order interpolation method to reduce input size, while the output are the TM010 frequency, axial electric field at $r=0$ for several axial points, and the scale factor used to normalize the electromagnetic energy. The model exhibits a good accuracy during training with less than 1% error, and could predict the relation between cavity radius and RF frequency for TM010 mode. For a cavity geometry not similar to training samples, such as elliptical cavities, the frequency error increased to almost 3% while the total error is about 8%. However, the simulation duration is significantly reduced compared to simulation using SUPERFISH, even when using suboptimal hardware. Thus the model might be useful for cavity geometry optimization using parameter sweep.
