calibcant

calibcant: tools for thermally calibrating AFM cantilevers

Calculates the spring constant k of a cantilever using the equipartition theorem:

1/2 k_B T = 1/2 K x^2

The analysis uses the expected power spectral density (PSD) of a damped simple harmonic oscillator to filter out noise from the measured PSD.

Installation

Gentoo

I’ve packaged calibcant for Gentoo. You need layman and my wtk overlay. Install with:

# emerge -av app-portage/layman
# layman --add wtk
# emerge -av sci-physics/calibcant

If you’re installing by hand or packaging calibcant for another distribution, you’ll need the following dependencies:

You’ll also need my pyafm and stepper packages, or suitable replacements.

Calibcant is available as a Git repository:

$ git clone git://tremily.us/calibcant.git

See the homepage for details. To install the checkout, run the standard:

$ python setup.py install

See the module docstrings for simple examples.

Run internal unit tests with:

$ nosetests --with-doctest --doctest-tests calibcant
