TUPWI001	Turnkey Systems Cost Optimization by Iterative Design of Magnets and Power Supplies	2239
	M. Cavellier, W. Beeckman, F. Forest, J.D. Holzmann Sigmaphi, Vannes, France
	For more than 30 years, Sigmaphi has been manufacturing magnets and power supplies. Its teams are now able to supply a complete particle beam line, from beam optics calculation to on-site installation and alignment. These combined skills allow design optimization for turnkey systems in order to reduce their purchasing and running costs. An example of successful iterative design is presented: a 70 meters beam line designed, manufactured and installed by Sigmaphi for JINR in Dubna, Russia. This design optimization allowed reducing total power consumption of the 14 quadrupoles by 7.5%.

	Funding: DE-SC0004254 Under an SBIR from DOE, Diversified Technologies, Inc. (DTI) has designed and built an advanced, high-voltage solid-state modulator for long pulse klystrons for ESS. In 2014, DTI, in partnership with SigmaPhi Electronics, received two contracts for production and installation of this design for ESS-class modulators, which will be used for the testing and conditioning of ESS klystron tubes and testing of RF components. This modulator design uses a hybrid configuration (solid state switch and pulse transformer) with an advanced switching regulator to maintain a very flat voltage into the klystron over multi-millisecond pulses. This paper will describe the design and testing of these modulators, and the status of their installation. The major development introduced in this design is that the millisecond-long pulses produce a droop voltage of about 10% with a reasonably-sized capacitor bank–much larger than the 1% droop required. To eliminate the droop without a large and expensive capacitor bank, the modulator uses a non-dissipative regulator.
