	The knowledge of the heat intake from the electron beam is essential to design the cryogenic layout of superconducting insertion devices. With the aim of measuring the beam heat load to a cold bore and understanding the responsible mechanisms, a cold vacuum chamber for diagnostics (COLDDIAG) has been built. The instrumentation comprises temperature sensors, pressure gauges, mass spectrometers and retarding field analyzers, which allow to study the beam heat load and the influence of the cryosorbed gas layer. COLDDIAG was installed in the storage ring of the Diamond Light Source from September 2012 to August 2013. During this time measurements were performed for a wide range of machine conditions, employing the various measuring capabilities of the device. Here we report on the analysis of the measured beam heat load, pressure and gas content, as well as the low energy charged particle flux and spectrum as a function of the electron beam parameters.

	The Transparent Realignment of the Diamond Storage Ring is a program of work to improve the mechanical alignment of the machine by carefully moving the magnet girders with a virtually zero impact on the associated beamlines. The girders can be moved by means of a 5-axis motion system under remote control via the EPICS toolkit from the Diamond Control Room. Currently three cells (three girders in each) have been equipped with a permanent protection system to prevent excessive deflection across each of the inter-girder vacuum bellows.

The Transparent Realignment of the Diamond Storage Ring is a program of work to improve the mechanical alignment of the machine by carefully moving the magnet girders with a virtually zero impact on the associated beamlines. The girders can be moved by means of a 5-axis motion system under remote control via the EPICS toolkit from the Diamond Control Room. Currently three cells (three girders in each) have been equipped with a permanent protection system to prevent excessive deflection across each of the inter-girder vacuum bellows. The protection and motion systems are installed in the associated Control and Instrumentation Area (CIA). Full commissioning of the motion and protection systems have been completed. Results from the alignment test sessions are hereby reported.
