Overview of the lab course

• Day 1 (9th of September): basics of C# programming (for everyone) Slides
  • Building a GUI, handling events
  • Basic file I/O
  • Communication with instruments over serial port or GPIB
• Day 2 (16th of September): more C# programming (for everyone) Slides
  • Real-time plotting
  • Using the NI myDAQ
• Days 3-5: experiment control exercises (for everyone, but scheduled on an individual basis)
  • Investigation of High Temperature Superconductors (SC)
  • Quartz sensor (QUARTZ)
  • Investigation of atomic contacts (ATOMIC)
• Days 6-13: lab experiments (depending on the specialization, scheduled on an individual basis)
  • Research physicist specialization: two out of the three measurements below must be completed. Each experiment takes a whole day (~8 hours starting from 8:30). Upon a justified request the measurement dates can be rescheduled once the measurement pair and the lab leaders can agree on a new date.
    • NMR
    • ESR (to be translated)

• • Nanotechnology and Materials Science specialization: the three measurements below must be all completed. The STM measurement takes a whole day (~8 hours starting from 8:30), whereas the Surface physics measurements take a half day each (~4 hours starting from 8:30). Upon a justified request the measurement dates can be rescheduled once the measurement pair and the lab leaders can agree on a new date.
    • Optical and Atomic Force Microscopy Examination of Two-dimensional Crystals (AFM) and AFM User's Manual
    • Surface physics 1 (SP1)
    • Surface physics 2 (SP2): SIMS and XPS

Locations

• Days 1-5
  • Lecture Hall F3211
• Days 6-8 Map

• • NMR: F I. basement 6., High-field NMR Laboratory
  • ESR: L ground floor (the entrance is facing building F, walk towards the fence)
  • AFM: ?
  • Surface physics 1-2: F III., mezzanine 4., Department of Atomic Physics, Surface Physics Laboratory

Installing Visual Studio

We use Visual Studio 2017 in the lab computers. For working on your own PC, download and install the Community edition of Visual Studio 2017 or 2019 from the link below:

https://visualstudio.microsoft.com/vs/older-downloads/

You should install Visual Studio with .NET workload.

Installing NI DAQmx

In case you would like to use your own PC for working with the myDAQ card, you also need to install the NI-DAQmx library. Download and install it from here: https://www.ni.com/hu-hu/support/downloads/drivers/download.ni-daqmx.html#348669

The installer has a lot of options. You will need NI MAX (Measurement & Automation Explorer), and .NET 4.5 support.

Lab report requirements

Submission rules

• The lab reports should be sent as a pdf file to the e-mail address of the lab leaders, as well as to the address.
• The file name should contain the names of the submitting students and the measurement exercise name using the format: stm_smith_white.pdf.
• The lab reports should be submitted within one week till Sunday midnight. In case of difficulties with the electronic submission the printed out reports are also accepted at the secretary of the Department of Physics till Monday noon.
• Once in a semester the submission can be delayed with a week without any punishment. Any other delay yields a subtraction of 15 points (< 1 week delay) or 30 points (> 1 week delay) from the final score (max. 100 points) of each delayed lab report.

Expected style of the lab report

The lab report should follow the style of scientific publications: short abstract, introduction, description of the applied measurement methods, description and discussion of the measurements, conclusions. Supporting information, like the key parts of the measurement code should also be submitted as an appendix. Special attention should be taken on the proper citation of the sources. Note that carefully edited figures are also key requirements in a high quality publication.
