\subsection{APS Insertion Device}
\textit{Platforms: Requires EPICS 3.14 support.}

\ \newline
This driver is used to control either the gap or the harmonic energy
of an undulator/wiggler insertion device at the 
\MxLink{http://www.aps.anl.gov/}{Advanced Photon Source}
\textit{(http://www.aps.anl.gov/)}.
These driver make use of the information found at the
\MxLink{http://www.aps.anl.gov/aod/blops/IDINFO/ID\_Controls.html}
{APS ID Controls Information}
(http://www.aps.anl.gov/aod/blops/IDINFO/ID\_Controls.html)
web page.

The only driver supported is:
\newline
\begin{tabular}{ll}
\textit{aps\_gap} 
	& - Controls either the gap or energy of the insertion device. \\
\end{tabular}

\ \newline
The record fields for this driver are:
\newline

\newcommand{\MxFieldApsZgapSectorZnumber}
{ The number of the APS sector that the insertion device belongs to.
For example, at APS Sector 10-ID, the sector number would be 10.}
%
\newcommand{\MxFieldApsZgapMotorZsubtype}{
	This field has four possible values: \newline
	1 - for gap control in millimeters.\newline
	2 - for ID energy control in keV.\newline
	3 - for taper control in millimeters.\newline
	4 - for taper control in keV.\\
