Students
If you would like to schedule a meeting with me, please see my calendar to find out when I am available. Send me an email the evening before of the day you would like to meet
Some tips for all students who plan to work with me
On writing and presentation of results
- How to make a presentation with impact
- Writing well: Strunk and White's The Elements of Style is an excellent handbook of writing style.
- After you have got the general idea on how to write well, a useful guideline to follow is Mark Twain's witticism: "If in doubt, strike it out".
Instrumentation for Particle Physics
Basic concepts
Nuclear Instruments and Methods in Physics Research Section A/B (NIM A/B) is the premier journal devoted to detectors and instrumentation in particle physics. This special issue consists of review articles of advanced detector and instrumentation technologies with a view towards future upgrades.
Our group focuses on wide bandgap semiconductor detectors. So please read up on (a) wide bandgap semiconductors (b) radiation detectors and (c) radiation before coming to see me to discuss a research project
Though you will see from the list of past students' work below that we often take up projects for their general coolness factor.
[MUST READ] Lecture Notes by Helmuth Spieler on Design of readout electronics:
- Analog and digital design
- Timing considerations.
- See also Helmuth Spieler's homepage with many other tutorials.
- An expanded version of the lecture notes has been published in e-book format Semiconductor Detector Systems by Oxford University Press (2007). It is available through the IIT-B central library. Chapter 9 of the e-book is especially usefully once you start building things in the lab.
- Semiconductor radiation detectors: device physics by Gerhard Lutz (Springer 1999) is another good book on the intrinsic detector response of semiconductors. Paper copies are available for issue in the IITB central library.
Good practices in Electronics Design and Circuit fabrication
Discrete large components are so old-school! Give in to the fact that you will have to work with SMD components. Here are a couple of video tutorials on soldering SMD PCB's:
Here are some guidelines for good PCB design.
- David Jones' elementary PCB design tutorial See also his website
- Some thoughts on how to choose a solder finish for your PCB - by the professionals
- Tim Jervis' note on electromagnetic radiation considerations in PCB design
- Cambridge Semiconductor application note on PCB layout (focuses on power supply)
- Handling high currents here, and here - yes the trace width matters! and there are rules about it!
Advanced topics on stray effects, capacitive loading from PCB traces and such
- Texas Instruments tech note by John Wu on precision Analog PCB design, with emphasis on how to avoid EMI pickup
- Texas Instruments guidelines for analog PCB circuit design (from the ebook OpAmps for Everyone)
- Analog Dialog 38-06 on how stray capacitive loading affects stability in opamp feedback circuits, and how to avoid it.
- Analog Dialog 12-83 on PCB trace layout for low noise analog and digital circuits (beware - an exhaustive/ing 97 pages!)
Advanced topics in RF and high frequency PCB design
- Super good tutorial notes on how to design PCB's for RF (~ GHz) range signal transmission from the friendly folks at Jefferson Lab Accelerator division, who hosted the much beloved, first EDA software P-CAD until it was bought out by Altium.
-
Roger's white paper on selection of PCB substrate for high frequency applications
- Tech note on calculating geometry of PCB traces for specific high frequency and microwave applications
- Texas Instruments App Note AN08 on low power RF PCB design
Some fun:
- A visual tour of the Advanced Circuits mass PCB fabrication facility
- A rambunctious video tour of the SparkFun science fair.

Resources for Learning Physics
This section does not endorse any particular resource. I have listed a few places where you can get a good, reliable basic education in Physics. Apart from attending classes and solving exam problems, that is!- The Theoretical Minimum A course taught at Stanford University by Leonard Susskind. Covers all areas of Physics. Video lectures are available. The corresponding e-book has problems that are insightful. IIT-B students would initially scoff at the (apparently) low level of problems. But try them out and see!
I have had the good fortune of working with some exceptionally gifted students. This is a list of my students and research assistants, past and present:
