	ALBA is a 3rd generation Synchrotron Light facility with: 8 operational Beam Lines (BLs), a 2nd BL of Phase II under construction and 3 first Phase III BLs in design phase. Some user experiments require Liquid Helium (LHe) as a coolant. The resulting LHe consumption at ALBA is about 650 l/week. Thus far the vaporized helium, which results from the refrigeration of experiments and equipment, has been released into the atmosphere without being reused. Due to the increasing price of LHe, ALBA agreed with ICN2 (Catalan Institute of Nanoscience and Nanotechnology) to invest in a Liquefaction Helium Plant. Internal staff has carried out the project, installation and pressure equipment legalization of the plant, which is located in a new 80 m2 construction. Under operation the plant allows recycling up to 24960 litres of LHe per year, which is an 80% of the helium consumed at ALBA, by making the gaseous helium undergo through 3 main stages: recovery, purification and liquefaction. The plant, unique in Catalonia, will entail cost savings about 77% and will reduce vulnerability to supply disruptions. ICN2 will benefit from a part of the production due to their initial investment.

WEPH30	Energy Efficient Air-Conditioning System Design	controls, photon, linac, operation	270
	Z.-D. Tsai, W.S. Chan, C.S. Chen, Y.Y. Cheng, Y.-C. Chung, C.Y. Liu NSRRC, Hsinchu, Taiwan
	At the Taiwan Light Source (TLS) and Taiwan Photon Source (TPS), several studies related to energy savings in air-conditioning systems are underway, where heat recovery has been considered for laboratory applications. The performance of a run-around coil has demonstrated that heat recovery plays an important role in energy conservation. Based on this design of an air handling unit (AHU), we enhance this model by combining it with enthalpy control for seasonal changes. Here, we construct a new AHU to verify the practical impact of energy usage. The improvements show that both mechanisms can be achieved simultaneously.

THOAMA01	Optimizing the PETRA IV Girder by Using Bio-Inspired Structures	lattice, synchrotron, radiation, storage-ring	297
	S. Andresen Alfred-Wegener-Institut, Bremerhaven, Germany
	The PETRA IV project at DESY (Deutsches Elektronen Synchrotron) aims at building a unique synchrotron light source to provide beams of hard X-rays with unprecedented coherence properties that can be focused to dimensions in the nanometer-regime. An optimization of the girder structure is necessary to reduce the impact of ambient vibrations on the particle beam. For this purpose, several numerical approaches have been made to simultaneously reach natural frequencies above 50 Hz, a high stiffness and a low mass. In order to define an optimal girder support, a parametric study was conducted varying both the number and location of support points. Based on the resulting arrangement of support points, topology optimizations were performed to achieve a high stiffness and a high first natural frequency. The following transformation of the results into parametric constructions allowed further parametric studies to find optimal geometry parameters leading to the aimed girder properties. In addition to that, bio-inspired structures based on marine organisms were applied to the girder which likewise resulted in improved girder properties.

THPH40	Training the Next Generation of Engineers for Photon Based Light Sources	synchrotron, survey, site, electron	421
	S.M. Scott DLS, Oxfordshire, United Kingdom
	The continued increase in the number of Light Sources, their beamlines and the need for upgrades of both machine and beamlines requires an ever larger supply of suitably qualified and experienced engineers. If there is a world wide shortage of Engineers where will facilities find these engineers and how can they be trained to the required level? This paper discusses these issues by looking at the growth of demand for engineers within light sources, the evidence of shortages of engineers, the changes in attitudes to work by younger people, the skills necessary, training opportunities and the issues in attracting people into the light sources industry. The paper will also outline the training week for early career engineers delivered at Diamond.
