Ionization Profile Monitors

Ionization profile monitors (IPMs) are widely used in accelerators for non-destructive and fast diagnostics of high energy particle beams. These monitors provide information of particle beam shape and dynamics. Profile monitors extract from the passing beam the vertical and horizontal distributions of the beam particles, be they electrons, protons or heavier ions.

Attendees will learn:

• The deposition of energy in matter, in this case the ionization of a background gas
• How shaped electrodes direct the ion pairs
• How an amplification of 10^7 converts single ions to a detectable current
  I will cover basic principles of energy deposition in matter, applicable to particle detection in solid-state detectors as well as single-event upsets in CMOS, electrode design for shaped fields, and ultra-high vacuum considerations for the use of materials

Speaker Bio:
Arnold Stillman is the founder and CEO of POEM Technology, a manufacturer of cellular IoT devices.

He has held senior engineering positions at Clever Devices, Tactronics and Brookhaven National Laboratory. Most of his professional experience was at BNL, where he designed instrumentation for particle accelerators and high energy physics experiments.

He is a past chair of the Long Island Section of the IEEE and is a member of the American Physical Society.

He is the author of several publications and has been a reviewer for The Review of Scientific Instruments. He is a graduate of the University of Rochester.

Agenda:
We will start our meeting at 7:00 pm. For the next 15 minutes or so, we will introduce ourselves and do a little networking. We will then start our presentation. After the presentation, feel free to stick around and chat with others to network or to further discuss our lecture topic.

NOTES
*** Because our normal first Thursday of the month meeting date would have conflicted with Rosh Hashanah, this meeting is being held on October 10, 2024. ***

There is no cost to attend this meeting, however, if you are a NYS Professional Engineer and would like to receive 2 Professional Development Hours (PDHs) of continuing education credit, then payment of a $15 fee is required. You will also have to properly fill out an Evaluation Form to prove that you attended this lecture. Click here to open the form. Simply fill it out and click on the “Submit” button.

We accept electronic payment via Zelle. Zelle is a bank-to-bank transfer mechanism supported by most banks, without a fee, as part of their normal online banking capabilities. There is also a Zelle app available for your smartphone.

When you use Zelle with your bank, it will ask for the following information: 1) the amount to send (enter $15.00), 2) what account you want to pull the money from (select whatever account you want to use), and 3) the phone number or email of the recipient (enter ieeelicn@gmail.com. Don’t worry if you see the name of our Treasurer, David Rost, pop up). If it asks for a memo field, we suggest entering "yymmdd LICN CEU” where yymmdd are the year, month and date of the lecture.

While we prefer that your payment and evaluation form are received by the day of the lecture, they must be received by the first Monday after the lecture.

If paying by Zelle is a problem for you, then please contact Ed Gellender at edgellender@gmail.com for an alternate payment method.
