Title: Sending-out method for light output decrease alarm
Inventor: TSUKAGOSHI TAKASHI
IPC: H04B10/07
Filed: 1989-01-23
Abstract: PURPOSE:To generate the light output decrease alarm when the peak value of a light output decreases by a constant value below the reference power irrelevantly to the mark rate of a modulated signal by varying a threshold voltage according to the mark rate by using the divided value of the mean voltage of the modulated signal without fixing an alarm generation threshold value. CONSTITUTION:The modulated signal which is inputted to a modulated signal input terminal 1 is sent out to an integration circuit 3 and a laser diode driving circuit 5. The output of the integration circuit 3 is the reference voltage of an automatic light output control circuit 6 and also divided by output resistances R2 and R3 of the DC amplifier 9 of a light output decrease alarm circuit 4 to become the alarm generation threshold voltage of a comparator 10 for light output decrease alarm generation. When the light output power decreases 3 dB below the reference power and an alarm is generated, resistances R2 and R3 are equal in value. A voltage Vp(=R 1XIp) obtained by converting the detection current Ip of a PIN photodiode 8 into the voltage is inputted to the minus-side input terminal of the comparator 10 for light output decrease alarm generation. When the peak value of the light output power is constant, the voltage Vp becomes constant at each mark rate.

Abstract: PURPOSE:To make the compression of a charged particle beam possible by exciting a deflection mode in a synchronization relation between the excited frequency of the deflection mode and the excited frequency of a high frequency acceleration cavity disposed in the charged particle beam orbit. CONSTITUTION:In the orbit of a charged particle beam 103 in a cavity 1, an electric field component is produced in the central orbital direction of the charged particles, while a magnetic field component is produced perpendicularly to the horizontal plane (the orbital plane), forming a deflection mode in the orbit of the charged particles in the cavity 1. Namely the deflection mode is produced which has the electric field component in the orbit of the charged particles and in the central orbital direction and has the magnetic field component perpendicular to the orbital plane. The deflection mode is excited, being synchronized with the basic acceleration mode in a high frequency acceleration cavity. The energy of the charged particle beam 103 is spread more widely and the emittance of a betatron oscillation is lessened for throttling the charged particle beam thin. In this method, the charged particle beam 103 is compressed down to several tenth.
