	The TPS is a state-of-the-art synchrotron radiation facility featuring ultra-high photon brightness with extremely low emittance. Its Booster has 6 FODO cells which include 7 BD dipoles with 1.6 m long and 2 BH dipoles with 0.8 m long in each cell. After magnetization of stainless steel vacuum chamber of the booster were identified and then dismantled, annealed, and re-installed, the electron beam energy of the Taiwan Photon Source (TPS) in the booster ring has ramped to 3 GeV in a week. The booster tune correction during ramping is one of the main reasons why the booster commissioning progress is so fast. In this paper the summarized the booster tune monitor system will be summarised

WEPGF050	Integrated Detector Control and Calibration Processing at the European XFEL	detector, controls, framework, software	814
	A. Münnich, S. Hauf, B.C. Heisen, F. Januschek, M. Kuster, P.M. Lang, N. Raab, T. Rüter, J. Sztuk, M. Turcato XFEL. EU, Hamburg, Germany
	The European X-ray Free Electron Laser is a high-intensity X-ray light source currently being constructed in the area of Hamburg, that will provide spatially coherent X-rays in the energy range between 0.25 keV and 25 keV. The machine will deliver 10 trains/s, consisting of up to 2700 pulses, with a 4.5 MHz repetition rate. The LPD, DSSC and AGIPD detectors are being developed to provide high dynamic-range Mpixel imaging capabilities at the mentioned repetition rates. A consequence of these detector characteristics is that they generate raw data volumes of up to 15 Gbyte/s. In addition the detector's on-sensor memory-cell and multi-/non-linear gain architectures pose unique challenges in data correction and calibration, requiring online access to operating conditions and control settings. We present how these challenges are addressed within XFEL's control and analysis framework Karabo, which integrates access to hardware conditions, acquisition settings (also using macros) and distributed computing. Implementation of control and calibration software is mainly in Python, using self-optimizing (py) CUDA code, numpy and iPython parallels to achieve near-real time performance for calibration application.

THHB2O03	The Global Trigger with Online Vertex Fitting for Low Energy Neutrino Research	experiment, electronics, detector, simulation	1107
	G.H. Gong, H. Li, T. Xue Tsinghua University, Beijing, People's Republic of China H. Gong TUB, Beijing, People's Republic of China
	Neutrino research is of great importance for particle physics, astrophysics and cosmology, the JUNO (Jiangmen Underground Neutrino Observatory) is a multi-purpose neutrino experiment for neutrino mass ordering determination and precision measurement of neutrino mixing parameters. A brand new global trigger scheme with online vertex fitting has been proposed, aiming at the ultra-low anti-neutrino energy threshold as down to 0.1MeV which is essential for the study of solar neutrino and elastic scattering of neutrinos on supernova burst. With this scheme, the TOF (time of flight) difference of photons fly through the liquid media from the interaction point to the surface of central detector can be corrected online with real time, the width of trigger window to cover the whole period of a specific neutrino generated photons can be significantly reduced which lessen the integrated dark noise introduced from the large amount of PMT devices hence a lower energy threshold can be achieved. The scheme is compatible, flexible and easy to implement, it can effectively extend the physics potential of the JUNO for low energy neutrino research topics.
