Place of installation: Mirrotron laboratory in Martonvásár/Hungary
Background: The Mirrotron Radio Frequency Quadrupole (RFQ) is part of a compact neutron source that is being built in Martonvásár Hungary.
The 2.5 MeV RFQ designed and built by Time Co, Ltd., Japan is a pulsed accelerator that can support 1.25 mS pulses at a rate of 40 Hz for a maximum duty factor of 5% . The RFQ can accelerate a peak beam current of 20 mA with an input RF power 260 kW at 200 MHz. providing an average beam power of 2.5 kW. The loaded cavity Q is 10,000 which results in a cavity bandwidth of 20 kHz.
The RFQ accelerator system can be divided into 5 major subsystems
Implementation: Each of the above mentioned systems has been integrated into Blinky-Lite. Commercial equipment such as vacuum pumps and gauges (i.e. Pfeiffer TC 400 turbo pump drive unit and TPG 366 gauge controller) as well as the 200 MHz power amplifier from R&K company were integrated using Blinky-Bus, a standard Blinky-Lite template for serial communication. For all other systems control hard- and software has been built from scratch.
A detailed description of the control system can be found here.

Benefit: Using Blinky-Lite, it was possible to provide a full-stack control system for the RFQ in short time (<6 months) and at reasonable cost.
Our offering: We are able to offer a complete RFQ control system consisting of the above mentioned subsystems. Individual subsystems, such as the timing or LLRF systems can be provided as well.
