WECOAA01	Tango Collaboration News	controls, feedback, site, diagnostics	16
	J. M. Meyer ESRF, Grenoble
	During the last years, the Tango collaboration was and is still growing. More and more users are requesting new features and developing new tools for Tango. Decisions whether the requested features will be implemented and whether new tools will be part of the Tango distribution need to be made. The organizational aspects of the collaboration need to be clarified as well as the decision making process for new developments. This paper will explain the collaboration, its organization and the decision making process as well as the latest facts and features around Tango. Some ongoing developments are the new code generation tool to allow inheritance in the Tango class structure, the new event system for high bandwidth event distribution and the Tango packaging to allow installation with a few clicks.

THPL004	A Discrete Hysteresis Model for Piezoelectric Actuator and its Parameter Identification	controls, simulation	127
	Y. Cao, X. B. Chen University of Saskatchewan, Saskatoon
	Hysteresis is an important nonlinear effect exhibited by piezoelectric actuators (PEA) and its modelling has been drawing considerable attention. This paper presents the development of a novel discrete model based on the concept of auto-regressive moving average (ARMA) for the piezoelectric-actuator hysteresis, and its parameter identification method as well. Experiments were carried out to verify the effectiveness of the developed model. The result obtained shows that the developed model can well represent the hysteresis of the PEA.

THPL008	CLS User Services Web Portal	feedback	139

	The Canadian Light Source (CLS) User Services Web Portal is a collection of web applications that allows users and staff to manage experiment proposals, complete safety training and submit end-of-run surveys. Each user wanting beam time must submit a proposal describing their experiment. Once submitted, the proposal goes through a peer-review process where it is either approved or rejected. All on-site personnel are required to complete safety training. Staff and users are provided with training modules which are completed online. Most training modules consist of two parts: the presentation and the exam. The exams are graded automatically and the results are stored. At the end of each run, users are encouraged to complete an online survey. The survey gives users the opportunity to provide feedback on what was good about their CLS experience and what can be improved to provide them with better service. This paper will give an overview of the design, implementation and capabilities of web portal.
