摘要： PURPOSE:To increase a response speed of a system so as to contrive improvement of accuracy by removing a fundamental wave component in an output signal of a phase difference detecting means by the first filter, and further attenuating a ripple except a fundamental wave changed into a DC signal by the second filter. CONSTITUTION:A phase difference between input signals A, B is obtained by digital circuit calculation by combination of flip flop 2a, 2b and an AND circuit AND. In this way, no higher harmonic wave component is generated, and a main cause of generating a ripple is only a fundamental wave component of the input signal. An output signal of pulse width in accordance with the phase difference between these signals A, B is input to a band elimination filter 3 and a low-pass filter 4 to apply a DC signal in accordance with the phase difference to an amplifier 5. When an output signal P of the flip flop 2a is input to the filter 3, here the fundamental wave component is removed from the signal P, and it is integrated by the filter 4. In this way, a phase difference detecting circuit of quick system response speed is obtained.

摘要： PURPOSE:To stably accelerate a beam by setting the response speed of a phase feedback system to be faster than a synchrotron oscillation, and the response speed of a position feedback system to be slower than that of the phase feedback system so as to mismatch the response speed to the synchrotron oscillation. CONSTITUTION:A phase feedback system that feeds the signal of a detector 6, which detects a difference between the phase of a beam and the phase of a high-frequency accelerating voltage in an accelerator, back to a main oscillator 1 and a position feedback system that feeds the signal of a detector 5, which detects a position deviation of the beam, back to the main oscillator are constructed. The response speed of the phase feedback system is set faster than a synchrotron oscillation, and the response speed of the position feedback system is set slower than that of the phase feedback system so as to mismatch the response speed to the synchrotron oscillation. Thus, the phase feedback loop suppresses fast oscillation in the direction that the beam proceeds, and the position feedback loop suppresses slow oscillation in the transverse direction of the beam. As a result, the beam can be accelerated stably.

摘要： PURPOSE:To make the inductive voltage a smooth continued value, lessen the deviation of the output value from the reference value under operation, and enhance the accuracy by tying two arbitrary points of the reference value of coil supply current as a function of time by an elliptic function curve. CONSTITUTION:Data of reference value is accommodated in a memory 3, and a power source 4 supplies current to a load coil 5 in accordance with the reference value. Reference value is given through intertalk by the use of a computer 1 and a CRT display 2. The diagram as illustrated is displayed on the display 2, and coordinates of Points P, Q and the gradient are given, and 4-degree simultaneous equations are solved by the computer 1 to determine the elliptic function [I=a+b{1-c(t-d) } ]. By the use of this function the numerical data about each time are obtained by the computer 1 and stored in the memory 3. Accordingly, Points P, Q are tied together smoothly when the power supply is in operation, and the voltage LdI/dt becomes continuous with respect to the inductive load, and the deviation of the output value from the reference value is lessened.

摘要： PURPOSE:To Improve file efficiency of a computer by storing data on the coordinates of each segment point and the functional form of each segment, in a memory of the computer. CONSTITUTION:When pattern data of an output set value (y) corresponding to a clock number (x) is to be stored in a memory of a computer, it is divided into a plurality of segments such as P0-P1, P2-Pn-1 at each point of the clock number, and the data is converted into the form of a function in which the coordinate of each segment point is matched with the change in each segment, and this information is stored in the memory. The data taken from an accelerator or a high frequency power source can be compressed by storing the data of functional form between the coordinate of each segment point and each segment, in the memory of the computer, and the amount of data is reduced. When pattern data is displayed on a display unit such as a CRT display, to form and correct the pattern data, the operation is carried out easily by designating only the coordinate of a segment point and a functional form. Efficiency of filling of the computer is thus improved, while formation and correction of pattern data are facilitated.
