Matt's Balmer Series Notebook

Safety

• The tubes are made of glass, and they should be handled with care.
• Glass tubes can get hot after even minimal use. Use caution when handling immediately after use.

Equipment

• Spectrometer - Adam Hilger; London, England; Serial: 12610
• Spectrum Tube Power Supply - Model: SP200 (5000V;10mA; Electro-Technic Products)
• Mercury Tube
• Hydrogen Tube
• Deuterium Tube

Set Up

• Place spectrometer and lamp on a sturdy, flat surface.
• Elevate the lamp to the point where the thinner part of the glass tube (while placed in the lamp) is level with the eye sight of the spectrometer. We used a stack of books.
• Fiddle with spectrometer until you obtain desirable cross hair position and general slit width.
  • Note: A thinner slit yields more accurate results, but sacrifices visibility.
