From dcchrist at wisc.edu Tue Feb 1 11:46:33 2022 From: dcchrist at wisc.edu (Daniel Christensen) Date: Tue, 1 Feb 2022 16:46:33 +0000 Subject: [labnetwork] UGIM 2022 is On. Call for papers. Message-ID: UGIM 2022 is on! The results from our survey indicate that we will go ahead and make a run at having the in-person meeting. We had 148 responses: 84 some level of yes/hopeful, 24 Unsure, and 40 some level of no/unlikely. Thank you all for answering and helping us figure out what to try for at 4 months out from the scheduled date. I will soon be touching bases with those of you that have volunteered for the program committee to check on your participation. We are once again issuing the call for papers. Jerry is emailing directly a list of previous attendees so this may be redundant for some. The UGIM 2022 (rescheduled UGIM 2020) Symposium (https://ugim2020.wisc.edu/) will be held June 6-9, 2022, at the University of Wisconsin-Madison. The symposium brings together educators and researchers involved in micro/nanotechnology and characterization lab management from around the world and provides a forum for exchanging information and presenting new lab operations and educational concepts. Representatives of micro/nano fabrication and characterization facilities, ranging from new labs to nationally and internationally recognized facilities, have found this symposium an excellent forum for exchanging information and networking. Typical topics include industry/university interactions, new equipment trends, best practices, collaborative research, and training efforts. Please submit abstracts for papers at https://ugim2020.wisc.edu/abstract-submission-2/. The deadline for abstract submission is 4/8/2022. Topics of interest include: Safety Staffing Financial administration Operations Growing your facility Education and training New facility startup Managing mixed use facilities Interacting with your administration Jerry L. Hunter and Dan Christensen University of Wisconsin-Madison, Wisconsin Centers for Nanoscale Technology Co-Chairs UGIM 2022 Daniel C.

(Fed)) Date: Tue, 1 Feb 2022 23:24:35 +0000 Subject: [labnetwork] Process Engineer or Microfabrication Scientist Message-ID: Dear Colleagues, The Fabrication Project (https://www.nist.gov/programs-projects/fabrication) within in the Quantum Sensors Group (https://www.nist.gov/pml/quantum-electromagnetics/quantum-sensors) at NIST (Boulder, Colorado) is seeking a Process Engineer or Microfabrication Scientist. The Quantum Sensors Group designs, fabricates, and tests detectors and readout electronics that achieve world class performance for microwave, x-ray, and gamma-ray sensing. Low temperature, superconducting, and quantum phenomena are harnessed to achieve extreme performance metrics. Example devices include the Superconducting Quantum Interference Device (SQUID), Transition Edge Sensor (TES), and Microwave Kinetic Inductance Device (MKID). The Fabrication Project utilizes the state-of-the-art Boulder Microfabrication Facility (https://www.nist.gov/programs-projects/boulder-microfabrication-facility). Candidates are expected to have an advanced technical degree and micro-fabrication experience, including direct handling of wafers. Equivalent practical experience may be considered instead of an advanced degree. A background in low-temperature device fabrication is desirable, but not required. The successful candidate is expected to become proficient in a range of micro-fabrication sub-areas including CAD layout, lithography, physical vapor deposition, and plasma etching and deposition. The successful candidate is also encouraged to play a major role in equipment maintenance, the acquisition of new equipment, process development, and the development and realization of new devices. We will consider both junior and senior level applicants. Interested candidates should contact Dr. Joel Ullom (joel.ullom at nist.gov). Founded in 1901, NIST is a non-regulatory federal agency within the U.S. Department of Commerce. NIST's mission is to promote U.S. innovation and industrial competitiveness by advancing measurement science, standards, and technology in ways that enhance economic security and improve our quality of life. The Department of Commerce/NIST is an Equal Opportunity Employer. Best regards, Shannon M.

In-Reply-To: References: Message-ID: Depending on your air handler design, you may be able to track HEPA life by monitoring amperage draw from the VFD's if you have it set at a closed loop ACPH setup. All acronyms aside, if you require something like 200 air changes per hour, you could baseline the air handler fan current and check it periodically. Some older clean rooms simply use the fan speed determined at the design phase, and let the HEPA's do their thing. This simple setup is easy to baseline and monitor as well. Our facility has a closed loop Variable frequency drive system coupled with particle counters in every chase to allow the room's particle count to dictate how much air is pushed through the filters. Our system would be difficult to monitor if we didn't have speed vs. amperage data since the speeds are constantly changing depending on the activity in the clean room. Makeup air amounts are not part of this equation since the makeup air is mixed with the circulated air and gets filtered with it. The amperage draw will tell if the filters are starting to load up. Most fabs have a HEPA life of decades is the pre-filters are changed often and the system is sealed as Deon Collins has mentioned.

In-Reply-To: References: Message-ID: <4082b0a0-ef61-7944-3eb2-e32202bf2c21@stanford.edu> Hi all - Cleanroom filters dating from the original build in 1986 at SNF were replaced in 2012.? There were two unanticipated benefits. First, the sound levels dropped -- a lot of people wondered if the laminar flow was really on. It certainly made for a more pleasant work environment.? Second, the electrical use in the building dropped.? It's hard to tell exactly what was attributable to the HEPA changeout because we also reduced some flow rates as well, but initial estimates were around 12% total reduction in electrical energy use versus before the project. So, there may be additional reasons for replacing HEPA filters, including the possibility that energy conservation programs may help with project costs. Mary -- Mary X.

Departmental Overview --------------------- The Space Sciences Laboratory (SSL) is an Organized Research Unit (ORU) of the Berkeley campus reporting to the Vice Chancellor for Research. SSL's primary goal is to foster research in space-related sciences and to provide education for the next generation of space scientists. Research at SSL, led by Berkeley faculty and SSL Senior Fellows, focuses on experiments and observations carried out in space as well as theoretical and basic research. Since its inception in 1959, SSL has participated in over 50 NASA space science missions, including the Apollo, Mars, Discovery, and Explorer programs, as well as many international space missions. SSL researchers have pioneered the development of instrumentation for study of the Sun, the interplanetary medium, the planets, and the Earth; for ultraviolet, x-ray, gamma-ray, and infrared astronomy; and for the measurement of the cosmic microwave background. SSL provides the engineering and technical capabilities required to develop and fabricate individual space instruments, an entire scientific payload for a spacecraft, or an entire space mission from start-to-finish-complete with in-house instrument design and fabrication; instrument and spacecraft integration and testing; launch support; mission and science operations, including commanding the spacecraft and bringing the data down to SSL's own ground station; and data processing and analysis.
