  1. Developing a user friendly Mass-scan program in Lab View Sam Bozek HSSRPP, Advanced Light Source August 8th, 2008

  2. Advanced Light Source • About Sam Bozek • Second Year of HSSRPP • Graduate of Albany High School • Freshman at Queen’s University • Pursuing a degree in Physics • I get my own Tam O’Shanter soon. It’s a Queen’s thing.

  3. Advanced Light Source • ALS • Electrons traveling near the speed of light in a forced circular path emit UV and X-Ray light that then shines down Beamlines to experimental endstations. • Beamline 10.0.01 • The Atomic, Molecular, and Optical Beamline

  4. Advanced Light Source • Mass Scans • The power supply sets the magnetic field of the analyzing magnet • The ion beam then hits the faraday cup, producing a current • The Current of the faraday cup is then measured with a Keithley 6517A Electrometer

  5. Advanced Light Source • The Equation • Using four equations (F=qvB, F=m*v^2/r, E=1/2 * mv^2, E=qΔV) one can derive an equation for a magnetic field that would force another ion along the same path an earlier ion traveled. • This equation turns out to be: • B2=B1*sqrt(m2q1/m1q2)

  6. Advanced Light Source • Then… • After that, the data is read from the power supply and Keithley and then put into the program • This gives a graph! • Y-axis is current from faraday cup, X-axis is the power supply’s current • .

  7. LabView • LabView • Uses a graphical programming interface • Can be used to communicate with a variety of instruments i.e. powersupplies, Keithleys • The Program: • Written in order to create a user friendly mass scan program that is adjustable.
