The Compact Ultrafast TErahertz Free-Electron Laser (CUTE-FEL) is being developed by BP&FEL Laboratory, RRCAT, which is designed to lase around 80 mm. Sub-systems like S-band high gradient accelerating structures, pre-buncher, buncher, pure permanent undulator etc. have already been developed and others are in advanced stage of fabrication/commissioning. In this paper we present the design, fabrication, measurements and status of various prototype developments of structures.

The 2.5GeV third generation synchrotron light source Indus-2 at RRCAT, which in advance stage of commissioning, demanded a high precision of survey and alignment of all its components. In particular, we had to control the transverse and azimuthal positions of all quadrupoles and dipoles within a relative accuracy of 0.1 mm and overall circumference within 2.5 mm. This required a tight control over all the sources of errors starting from fiducializations, survey of networks, final alignment and smoothing. We have successfully accomplished this task by adopting the triangulation-trilateration technique of survey and alignment along with indigenously developed software for online survey data collection, least square adjustment of redundant measurements and error analysis. The accuracy of alignment was reflected from the successful circulation and storage of electron beam in the machine with a very small closed orbit distortion. This paper, in brief, presents the methodology adopted for survey and alignment and final accuracies achieved.

The Synchrotron Radiation Sources consist of a large number of components of varying nature. Some components are light but highly delicate whereas some are big and heavy. However all components need a careful handling during their installation. Unit-cell mock-up assembly and virtual simulation of the installation process using software tools contributed significantly in visualizing various handling schemes, checking interferences and defining the assembly sequence. We have recently completed the installation and integration of 2.5 GeV Synchrotron Radiation Source, Indus-2, by adopting a set procedure of installation and pre-defined sequence. This paper presents, an overview of procedures, sequence of assembly, equipments and toolings used for material handling and safety precautions taken during the whole task of installation and assembly.
