The tile endcaps [20] were installed into OPAL in 1996, and perform the same function in the endcap region as TB does in the barrel region. TE consists of 10 mm thick scintillating plastic tiles. Embedded in the tiles are wavelength shifting optical fibres. It has a timing precision of about 3 ns and covers the region close to the beam pipe. It is an essential detector in both exotic particle searches and two photon studies. An extension of TE, the Minimal Ionising Particle (MIP) plug was installed in 1997, and gives coverage of the polar angular region down to 43 mrad from the beam pipe.
