Faculty candidate seminar - Tuesday, April 28th, 2:00 pm in Wang 1004
by Anthrop, Heather L 27 Apr '15

Alan Hoskinson Research Assistant Professor Department of Electrical and Computer Engineering Tufts University College of Engineering Faculty Candidate: Cold Plasma Team Tuesday, April 28th at 2:00 pm WANG 1004 Control of high-frequency microplasmas for materials and optical applications Using microwave power to generate plasmas at or near atmospheric pressure offers several advantages over comparable techniques: high steady-state electron densities, low voltage requirements, and extremely stable operation. The development of "cold" atmospheric-pressure plasma sources promises to open up new applications in areas from materials processing to medicine to chemical analysis. The high-energy electrons in the plasma can drive chemical reactions while the gas and substrate remain cool. In this talk, I discuss techniques for manipulating such plasmas to achieve the desired properties. The plasma structure can be altered by pulsing the microwave power, the electron density and plasma impedance can be adjusted by varying the drive frequency, and individual plasmas in an array can be switched on and off using solid-state circuitry. The plasma properties in these systems are characterized by applying an array of spectroscopic and electrical techniques. The high electron densities and stable operation make microwave-generated plasmas well-suited for applications requiring rapid generation of excited chemical species. Here I present exploratory studies in two such areas: rapid deposition of diamond-like carbon films, and the integration of microwave plasmas into a rare-gas laser system. Alan R. Hoskinson is a Research Assistant Professor with the Electrical and Computer Engineering Department at Tufts University. He obtained the Ph. D. degree from the Engineering Physics Department at the University of Wisconsin-Madison in 2009, specializing in the physics of dielectric barrier discharge operation. His research interests are in diagnostics and applications of "cold" plasmas, particularly when operating at atmospheric pressure. Recent investigations have included studies of control of microplasmas using solid-state electronics, development of spectroscopic analysis techniques, and engineering discharge systems for use in film deposition, chemical generation, gas-phase lasers and other applications.

Conference rooms Electrical Work Lab 1217 Cleanout Complete Preventive Maintenance Shut Down PROCESS FOR USING E-BEAM LITHOGRAPHY SYSTEM AT OTHER FACILITY Workshop Conference rooms Please remember that conference rooms are shared space and everyone should pick up after they use the room. If you move chairs and tables put them back where they belong. If you are going to move chairs from another room please check the schedule to make sure a meeting is not taking place before you are able to put the chairs back. Electrical Work During our PM shutdown scheduled for week of May 4, 2015 Physical Facilities electrical department will be completing major modification to the isolation grounding system in all general laboratories. Outlets in the laboratory with a label starting with "S" will be powered down 8 a.m. Monday, May 4 through 4 p.m. Friday, May 9 or until all modification are completed. Please move any critical tools requiring power during this shut down from the "S" outlets to the outlets starting with "N". [cid:image002.jpg@01D06220.1D6CF5E0] Lab 1217 Cleanout Complete The chemical cleanout of Lab 1217 is now complete. Ira Young has set aside the chemicals, and will hold them for two weeks prior to sending them to REM for disposal. If you need one of these chemicals please see Ira within the next two weeks. Also, during the PM shut down week of May 4th, the cleanroom will be cleaned out of old chemicals using this same process. Preventive Maintenance Shut Down The Birck Nanotechnology Center will be undergoing a semi-annual preventive maintenance and service shutdown May 4 through May 8, 2015. Air handling systems, exhaust systems, hazardous gas delivery, and monitoring systems will be down beginning at 7 a.m. Monday, May 4 through 4 p.m. Friday, May 8. The BNC staff will be performing appropriate preventive maintenance on the process equipment at this time as well. All CLEANROOM research work will be suspended until the maintenance activities are completed and all systems are returned to normal. No one will be allowed to enter the cleanroom during this time period. In addition, the laboratory areas will also be affected by this systems maintenance. As such, all LABORATORY activities that involve exhausted hoods, vacuum systems, and/or toxic gas systems will be down beginning 7 a.m. Monday, May 4 through 4 p.m. Friday, May 8. No chemical work will be allowed during this period.

I believe every research group using or planning to use Surface Analysis characterization tools should have at least one trained student. 1) Introduction to XPS workshop - What you should know about X-ray pohotoelectron spectroscopy (https://purdue.qualtrics.com/SE/?SID=SV_2aEjFISmtrn3IlD) May 19-20 @ 9:00 AM - BRK 1001. Course Description: XPS is widely used to determine the chemical composition of a surface (element concentrations, chemical states, lateral and depth distributions, etc.). Nowadays XPS has become a standard technique for the characterization of solid surface. The course will teach how and what information can be provided by XPS. 2) XPS Lite Workshop Introduction to CasaXPS (https://purdue.qualtrics.com/SE/?SID=SV_4ON5fLuUSipSyuV) May 26-27 @ 9:00 AM - BRK 1001. Course Description: XPS is widely used to determine the chemical composition of a surface (element concentrations, chemical states, lateral and depth distributions, etc.). Nowadays XPS has become a standard technique for the characterization of solid surface. however, XPS data require thorough analysis, and dedicated software is used for data analysis. Purdue University has a site license for CasaXPS allowing complete analysis XPS data. The course aims to teach (1) what analysis should be applied to raw XPS data and (2) how this can be done using CasaXPS.
