 \section{Design goals}
 
 For the dynodes supply of a \emph{Photoelectron Multiplier Tube} we
 need a sinus function voltage with an amplitude of about
-$U_{\mathrm{OUT}}=50\units s$ to drive a Cockcroft–Walton cascade.
+$\Uout=50\units s$ to drive a Cockcroft–Walton cascade.
 
 In the output terminal shall be a capacitor $C_2 \ge 100\units{pF}$ to
 account for capacitive loads.
