Scientific and Industrial Case Histories


Brookhaven National Laboratory EBIS Project

Continental Electronics designed, manufactured, and delivered to Brookhaven National Laboratory two RF Power Amplifier systems operating at 100.625 MHz, each producing 350 kW peak-power pulses. The Power Amplifiers, designed and built specifically to Brookhaven’s specifications and awarded to Continental by competitive contract, are to be employed as part of the Electron-Beam Ion Source (EBIS) program.

The Electron-Beam Ion Source (EBIS) program has been proposed by Brookhaven scientists to provide a replacement for the present Pre-injector in Brookhaven’s Relativistic Heavy-Ion Collider (RHIC). The new heavy-ion Pre-injector will be comprised of the high charge-state ion source and a Radio Frequency Quadrupole (RFQ). The new pre-injector will be a reliable, low-maintenance Linear-Accelerator (linac)-based facility. Linac-based pre-injectors are now used in many other accelerator and collider facilities.

Each of the RF Power Amplifier systems supplied by Continental operates at 100.625 MHz, and each produces 350 kW peak-power pulses for the RFQ and the Linac. Pulse duration is 1 millisecond, and pulse repetition rate is 5 pulses per second.

 


Brookhaven National Laboratory, ERL Project

Continental Electronics delivered to Brookhaven National Laboratory (BNL) an Integrated 1 MW Klystron Transmitter and 100 kV High-Voltage Power Supply (HVPS). The system was designed by Continental Electronics and manufactured under a competitive contract from BNL. The Transmitter and HVPS system are integrated with a 1 MW CW klystron operating at 704 MHz. The equipment is part of an ERL (Energy Recovery Linear accelerator) experiment to be conducted at BNL. The ERL is planned as an improvement to the Relativistic Heavy Ion Collider (RHIC) facility. The HVPS is based on Continental Electronics’ Crowbar-less IGBT High-Voltage Switching supply design and provides up to 100 kV at a full-load current of 21 A for the 1 MW klystron Transmitter. No crowbar circuit is needed because the solid state switching approach leaves little stored energy to be dissipated during a fast shut-down event. In addition to the HVPS, the integrated Transmitter system includes PLC controls and interface, water-cooling and monitoring system, high-voltage oil tank assembly, klystron and magnet supplies, and a custom designed user interface, as well as all safety interlocks, monitoring, and operational features.

 

Korean Atomic Energy Research Institute, Fusion Project

Continental Electronics delivered a special purpose cavity amplifier for the 30-60 MHz frequency range, capable of operating at up to 2 MW power output in long pulse mode. The system will be used for the Korean Superconducting Tokamak Reactor (KSTAR) in Daejon, Korea. It is based on a proven design built by Continental Electronics for a number of customers engaged in fusion research. Continental’s system includes intermediate, driver, and final power amplifiers, all power supplies, water-cooling for all stages, crowbar and switchgear. The transmitter, shown below, has been operated at 2 MW (megawatts) for up to 300 seconds in pulse duration.

 

HAARP

Another large program of great scientific interest is HAARP, an Ionospheric Research Instrument (IRI) located in Gakona, Alaska. The system consists of 360 transmitters provided by Continental Electronics. The transmitters are configured as matching pairs of power amplifiers driving a set of crossed dipole antennas. The construction of the HAARP system was completed in several phases from prototype through final production. Continental designed the transmitters specifically to the HAARP requirements using several field proven components from our extensive portfolio of transmitter related products. HAARP is an excellent example of our unique ability to apply products and manufacturing techniques from different transmitter types to meet special program requirements while minimizing technical and schedule risk.

 

Arecibo

Continental Electronics has earned recognition in scientific circles with its 1MW planetary radio transmitter, a key component behind the Arecibo Observatory's radio telescope. The Arecibo radio telescope is the world's largest single-dish radio telescope. With the support of CEC's engineering expertise, NASA scientists were able to map the moon in preparation for the historic lunar landings.
