\section{Calibrating the 407A}

Calibrating the 407A

You may sometimes notice that the zero position changes dramatically from sensitivity to
sensitivity with the 407A. If this happens, iterate through the following until zero stays
consistent:

Use the fine adjust (knob on side) to zero the 407A on the highest sensitivity

Use the front adjust (flathead screwdriver needed) to zero on the lowest sensitivity

\section{Lytron Kodiak RC006}

We have one Lytron Kodiak RC006:
Model Number RC006G03BB1C002
Serial Number 739383-02

Regular Chiller Maintenance:
\begin{denumerate}
  \item Gather supplies.
    \begin{enumerate}
      \item 1 gallon distilled water (do not use deionized)
      \item 1 gallon Nalco 460-PCCL104 (the pink stuff)
    \end{enumerate}
  \item Drain system completely.
    \begin{enumerate}
      \item Turn off chiller.
      \item Break tubing at push-to-connect, plugging return.
      \item Allow chiller to run until liquid stops flowing. You will get a pressure error, ignore
        (silence) it.
      \item Use tube to mouth-syphon remaining liquid from within chiller
      \item Reconnect at push-to-connect
    \end{enumerate}
  \item Fill chiller with distilled water (should require <1 gallon), let run for 30 minutes.
  \item Drain system again.
  \item Replace filter.
  \item Fill system with one gallon Nalco 460-PCCL104 (the pink stuff).
  \item Turn chiller on, top-off with distilled water.
  \item Record maintenance, order new supplies for next time if necessary.
\end{denumerate}

In the past we have had trouble with low flow errors upon system startup.  %
These seem to have been fixed by adding a “high” flow loop connecting the outlet and inlet of the
chiller.  %
Ideally the pressure drop across this loop is sufficient to still drive fluid through the laser.  %

\section{PolyScience 6000 Series}

We own two PolyScience chillers---different models but functionally equivalent.

Grey: Serial Number 3E1161245

White and Blue: Serial Number 4K1050550

Regular Chiller Maintenance:
\begin{enumerate}
  \item Gather supplies
\end{enumerate}

maintenance directions
Gather supplies
Filter - sold in the stockroom
1 gallon of Nalco 460-PCCL104 (the pink stuff)
Drain system completely
Disconnect red water line and allow chiller to pump water out.
Push nipple of male end with flat object so check valve is released
Take off of filter
Push down to allow water out
Check filters
If air filter dirty, wash with water (let dry after washing)
If water filter is dirty, replace
Reassemble, fill with Nalco 460-PCCL104 (the pink stuff)
Turn chiller on and top-off.

Visible Grating.  %

Align the HeNe as perpendicular as possible to the monochromator entrance slit.  %

Move the grating angle until the HeNe falls on the exit slit.  %

Shine a flashlight through the entrance slit and observe the colour on the exit slit: if white,
then you are at 0-order (0 nm), if red, then you are at 1st order (632.8 nm).  %

Go to 0-order, narrow the slits, and slowly adjust the angle until the HeNe is going through the
exit slit.  %

Go to Jovin Yvon/utilities and find the motor configuration program.  %

In the Gratings tab, select the 1st grating (1200 line density) and hit Calibrate.  %

In theoretical wavelength, enter 0 nm.  %

In experimental wavelength, enter the wavelength you observe from the control program.  %

Hit set. %
