Title: Development of a multi-PMT optical module prototype for PINGU

The multi-PMT digital optical module (mDOM) contains 41 three-inch{sup 2} PMTs in a cylindrical glass vessel. The design is based on the KM3NeT DOM. Among other advantages, this approach offers a significant increase of photocathode area per module and also per string length. As an R and D activity targeted at potential future extensions, this new type of optical modules will be tested in the framework of the PINGU project (Precision IceCube Next Generation Upgrade). PINGU will add denser instrumentation to the IceCube/DeepCore sub-volume aiming at a further decrease of the neutrino energy threshold (to a few GeV). The current status of the development and the prototype construction is presented.
