1. Introduction

A special purpose machine for the assembly of optical elements required for a Hard X-

ray Telescope is to be designed and fabricated as per the specifications and

parameters of the telescope as given below under the head of "Specification of

machine"

Hard X-ray telescope is basically a glass segmented X-ray optics designed for the

focusing of high energy X-rays (6 to 79 KeV) with a focal length of 6500 mm. This

telescope consists of an array of two co-axial and co-aligned segments of very thin

glass strips of width 20 mm and length 200 mm (for each segment). There are around

100-130 layers of very thin (0.3 mm thick) thermally formed glass substrates coated with

Si and W in a multilayer sputtering machine constituting an optical element. The

thickness of each optical element would therefore be 0.3 mm + a few microns of

thickness of the multi-layer coatings. Each of these optical elements is to be held very

precisely and rigidly in a pre-determined position by epoxy and graphite spacers.

The two optical modules collect the incoming hard X-rays via grazing incidence

reflection at the mirrors and focus them on to an imaging detector. The optical design is

a conical approximation to Wolter-I geometry of the mirrors aligned and held together by

epoxy and precisely machined graphite spacers that run along the optic axis. See

Figure 1 [Note: Focal length for our telescope is 6.5 metres and not 10.14 m as shown.

The length of each of the red and blue line segments is 200 mm with possibly a small

gap of a few mm (max 10 mm) in them. The details of the radii for each shell made from

segments of the mirrors for both the upper (1-alpha) cones and lower (3-alpha) cones

are given in two attached files “om_con1a_xhet01.doc” and “om_con_3a_xhet01.doc”

respectively: Annexures 1 and 2]

Figure 1

2. Requirements of the Assembly Machine

To assemble upto130 layers of concentric and co-axial glass strips (mirrors) we have to

make a custom built assembly machine. The entire assembly of all segmented mirrors

is to be built on this machine. All mirrors are aligned and supported by the central

mandrel of diameter 90 mm (this corresponds to the 24th shell or row number in the txt

files mentioned above, instead of the 1st shell) and manufactured from aluminum block

which will form the first or innermost shell. Each layer of mirrors is separated by graphite

spacers which are to be machined by a single point tool or grinding. A very high

precision of 1 micron or less is required for machining the graphite spacers and

aligning the mirrors. Please see Figure 2 below to understand the optics assembly

basics:

Step-1: Bond Spacers to Layer-1 Step-2: Machine Layer-1 Spacers

Step-3: Bond Layer-1 glass and Step-4: Machine layer-2 Spacers

Spacers for Layer-2

Figure 2

After construction, support spiders are to be attached to the optics for integration.

During the fabrication, glass and graphite layers are to be built outward from the central

mandrel and all ground handling and alignment activities will use the inner mandrel as a

support and the reference axis. Once all the mirrors for each shell are mounted to the

telescope bench, each is to be supported and aligned from an attachment point on the

spider supports.

The assembly machine to be built should comprise of precision air bearing axes

mounted on solid granite base and provide exceptional machine tolerances as shown in

a separate sheet (Annexure 3: Assembly Machine Error Budget). This machine is to be

installed in a 1000 class clean room with temperature and humidity control and the air

bearing machine components require no oils that could potentially contaminate the

optics. In this process nominally cylindrical glass segments are forced to a conical form,

and in the process radial mismatches are removed. Graphite spacers are first stuck with

epoxy (glued) to the mandrel and then precisely machined to the correct angle and

radius required for the optics. Next, a layer of multi-layer coated glass mirror and a

second layer of graphite spacers are stuck with epoxy to the first set of spacers. These

spacers are then machined to the appropriate radius and angle. This process is

repeated until the requisite number of layers is assembled. One important point of this

process is that each layer of spacers is machined with respect to the central optical axis

and not the last layer of glass. One has to avoid any cumulative errors during the

telescope fabrication. Other requirements in this machine are to arrange for automatic

collection of dust generated during the machining of the graphite, a fly cutter with air

bearing spindle and LVDT control.

One should also address the specific cutting tool (single point or grinding), tool set

station (Touch off, sacrificial, sensor based etc.), wagon wheel design and most

cruciallythe optics support during machining and for sectional integration. A conceptual

sketch of the machine is shown below in Figure 3 followed by some photographs of a

similar machine in Photographs 3(a), (b) and (c)

after the curing of one layer of mirrors or optical elements.

2a. Specifications for the assembly machine:

Our requirement is to build a CNC Contouring 3-Axis machine (may be a Lathe) with

three degrees of freedom: two translation and one rotary. The specifications required

are as follows:

Longitudinal table travel 460 mm (18”) (parallel to x-ray axis) – Straightness 0.6 μm (24 μinch) – Motor driven with speed control

Cross slide travel 280 mm (11”) (radial direction) – Straightness 0.4 μm (16 μinch) (factory spec)

– Motor driven with speed control

Tool geometry: fly cutting or single point turning – by a

diamond tool mounted in 4” PI block head air bearing spindle.

Rotary Table

-– Motor driven with speed control

Air bearing optic mandrel supports. – Air driven motor for spinning optic during single pointing.

(Max Speed = 300 rpm. Manually started – Azimuthally indexed air bearing spindle for metrology – Air bearing spindles aligned to 5 μm horizontally and 5 μm vertically

– Spindles are cones in conical seats in the optic. Repeatable to better than 5 μm.

Single Point Tool or fly cutter for giving conical shape to the graphite spacers.

Dust collection provision should be there to extract the graphite powder and to

avoid contamination on the optics.

Note: There should be a massive granite machine base, proper vibration

isolation and PC based control system. Accuracy and tolerances should be met

as per the requirements. Please see Annexures 4 and 5 (BOM_ASSM 1-1.pdf

and DIMENS_ASSEM 1.pdf files for the dimensions of the machine)

2b. Major functionalities of the machine

1. To assemble multi-layer coated thin glass sheets/mirrors in concentric and co-axial arrangement. The assembly with pre-specified separations from one optical element to another and built with segmented mirrors forming mirror shells is to be built in this custom designed machine.

2. All mirrors are to be aligned and supported by a central aluminum mandrel of diameter 90 mm.

3. Each layer of mirrors is separated by graphite spacers who are to be machined by a single point tool or grinding. A very high precision of one micron or less is required for machining the graphite spacers and aligning the mirrors.

4. After construction, support spiders are to be attached to the optics for integration.

5. During fabrication, glass and graphite layers are to be built outward from the

central mandrel and all ground handling and alignment activities are to use the

inner mandrel as a support and reference axis. Once these components are

mounted to the telescope bench, each is to be supported and aligned from

attachment point on the spider supports.

6. The assembly machine to be built should have precision air bearing axes

mounted on solid granite base and prove exceptional machine tolerance

requirements.

7. This machine is to be installed in a 1000 class clean room with temperature and

humidity control.

8. The air bearing machine components require no oils that could potentially

contaminate the optics.

9. Graphite spacers are first stuck by epoxy material to the mandrel and then

precisely machined to the correct angle and radius. Next a layer of glass and

second layer of graphite spacer are stuck by epoxy material on top of the first set

of spacers. These spacers are then machined to the appropriate radius and angle.

This process is repeated until the requisite number of layers is assembled.
